I’m not a big fan of yellow sockets. They throw me for a loop. And from looking at other disc priests, it seems there’s plenty of disagreement about what to put in your yellow sockets.

Here’s what I’ve got in my yellows right now:

2 runed
1 reckless
1 luminous

And I just socketed over one potent. What gives?

Lucky for me, I’m only interested in one thing at the moment: 25-man bubble-botting discipline. Poor Dawn, having to recommend gems for all purposes, all playstyles. I have it easy!

But first, a blog post

I wrote my last post right after giving up on guilds on my server. The one guild of interest to me hadn’t responded to my app after two weeks, so I interpreted that to mean “no thanks.” Well, the day after I posted I got a tell from their recruitment officer, and 15 minutes later had a ginvite. Many thanks to my future wife for going to bat for me. (She doesn’t know it yet, shhh.) So now I’m back to raiding, doing 7/12 hard modes. Sweet!

And my move across country is pretty definite, but won’t happen for another five weeks. So I have some quality raiding time before…well, I don’t know what will happen then.

Stats for bubble bots

Wait, haven’t we covered this before?

Why yes, yes we have. I apologize if this is redundant for you. The following analysis only applies to 25-man bubble-spamming disc priests. No other healing scenario lends itself to this kind of oversimplification. Under normal circumstances, you’ll be casting 9 shields and PoM, rinse & repeat. Obviously you’ll cast the occasional Penance, or Pain Suppression, whatever. So this is not exact, but it gives a fine approximation, which is enough for our purposes.

Do not try this for holy. Do not try this for 10-man disc healing. Or for any other healing spec. Healers are not like DPS classes; we cannot be reduced to Patchwerk-style simcrafting.

Haste: Because of the way Borrowed Time works, bubble-spamming disc priests need about 150 haste rating to reach the soft cap, which is where your GCD hits its minimum of one second. You probably had this much haste the day you hit 80 and are scary past that now. Therefore haste has zero value for a bubble bot.

Crit: Power Word: Shield can’t crit. But its glyph can. So you get 20% value for crit. PoM bounces can crit, of course, but you get five bounces (at most) per nine shields. So we’ll boost the value of crit by half to 0.3. Good enough for science.

Spell power: Your shields grow by about 1.5 hit points for every point of spell power. (Yes, that’s where all of our talent points are going!) This is our super-stat for super-sized shields.

So, to sum it up:

Spell power = 1.5
Crit = 0.3
Haste = 0

And you can fill in your own stat weights for intellect & spirit.

Luminous

I’ve been using Halion for the last week or so. It matches nicely with my other crit/haste gear, of which I have a ton. It also looks awesome.

The thing is, once I got it I started OOMing on every fight, 10 or 25, with or without replenishment. (That’s because I’m always casting!) Even doing my best to abuse the Rapture bug, I still popped more mana pots and begged for more innervates than I have in a long time. Thanks to Matron for indirectly kicking my butt.

So I gemmed full luminous in all my red and yellow sockets. And did not regret it one bit, despite the insane amount of conformism and peer pressure amongst disc priests to gem runed only, ever.

What’s the numeric value of luminous? It only has value if you need the mana. If you don’t, it’s obviously the wrong gem to use. In fact, last night I got a new staff, Heroic Dying Light. It has so much additional intellect, and an ungainly amount of spirit, that after using it for a few fights (including LK25) I’ve decided to drop my luminous gems for runed. So far so good. (And yes, I am still always casting!!)

Reckless

There are two reasons to socket haste: First, haste is an excellent stat for 10-man tank healers. If you do both 10 and 25 seriously then reckless is a viable gem to use.

The second reason is that haste is the best yellow stat for shadow priests. Any piece of gear you share with shadow will likely have reckless in it.

For bubble-bots though, haste is useless. If those two conditions don’t apply to you, reckless is kryptonite. Don’t touch it.

Potent

Crit is also an excellent stat for 10-man tank healers. And for bubble-bots, well, it’s not terrible, but it’s still not very good. It has about 1/5 the value of spell power, which means you’d need an unreasonably good socket bonus before using a potent gem for your bubble-spam role. Bottom line: probably not.

(This article is required reading if you want to know the relationship between crit & haste for disc priests.)

Summary

As you can see, a lot depends on what you do when you’re not bubble-botting. If you have more than one job, you’ll need to prioritize your gemming towards one or the other.

And remember, gemming is a minor component of your healing!

Full-time bubble-bot: You have only two choices. Runed or luminous.

Bubble-bot / 10-man: You have three choices: Runed , luminous, or reckless. Potent is also acceptable.

Bubble-bot / Shadow: You have two choices: Runed or reckless.

Ah, the flow chart!

Blue sockets?

Muahahaha.

Exercise for the reader.

One of the smartest members of the priesthood has done an excellent write-up of how crit and haste play out in practice. Well, in theory. In theoretical practice. Go check it out—Zusterke has done a splendid job of exposing the interlocking mechanics of these two stats.

He's concerned primarily with tank-healing throughput, which is of course what these two stats are all about.

TL;DR? Not sure I want to do this at all, because the article is not that long, and it's very well written. He quickly shows how a balanced profile gives the biggest boost to HPS, but that crit is slightly superior overall. Don't just take this over-simplified conclusion for granted though; his article is very nicely done and a fascinating read. I love good thinking!!

Enjoy, and have a safe & happy new year!

(The limb upon which I step grows thin and weak. It begins to creak under my modest weight, threatening to send me to the lions roaring below. Fade…levitate…don’t fail me now!)

Graduate-level? That’s right. This is not a guide for the fresh 80, although if that’s you, hopefully you will find it interesting nonetheless. For reference, here is the short and long form of Disc Stats 101 for the Up & Coming:

Q: OMG HELP!
A: Stack more spellpower and intellect.

There you go. See you in a couple of months.

This is also not a guide for the PhDs among you. You’ll know what you need better than I could ever tell you. Go read another analysis of the HPS and HPM of Greater versus Flash Heal and report back to me.

This is a guide for the rest of us. Geared enough to be confident, smart enough to be willing to adjust to changing situations.

Preface

First of all, this guide wouldn’t be needed without the Great Penance Nerf of ’09. Simple as that. Prior to that, our HPS (yes, I said it) was excellent. But with the extra time between casts of the best healing spell in the game (I said that too), our healing has changed. I’m no longer able to comfortably keep up a tank the way I used to. Other healers have been buffed, we’ve been nerfed. I’m not here to complain, but to discuss how to adjust, by selecting the proper stats for your gear and gems.

Second: any playstyle recommendation is totally dependent on the context. Are you over-geared for the content you’re in? Are you running with druids or with pallies? Are your other healers shit-hot at what they do, or do you end up carrying some of their weight? And on and on…I’m convinced that when you add up all of those factors for any group and for any encounter, there actually is a single correct response to the situation. By that I mean there is a correct gearing plan and a correct spell selection. But because the factors are so many, it’s impossible to nail down a single overarching recommendation. You just need to be smart and flexible.

Third – and last comment before we get started – the days of min/max are behind us. You can ignore everything you read here and anywhere else and still do well for the most part. If you enjoy improving your play (as I do), and don’t build computer simulations to evaluate specs and spell priorities, then read on.

Ok. Let us begin.

A few priests to consider

Wandering the hallowed halls of the interwebz I stumbled across a few priests that caught my eye. These are all folks with Algalon under their belts, in the top echelon of the priesthood. These are not necessarily the top three priests in the world, but they’re obviously smart, creative, well geared, and in the top strata of what they do. All values are taken straight off armory, so no buffs.  I’ve linked their profiles, but who knows what changes they will have made since I saw them.

Oh my. One stacked crit beyond what most people consider normal. One is an unabashed intellect stacker. And one stacked spellpower and haste. Who do we listen to?

The rest of this post is about the stats you can stack, why you would stack them, and why you’re nuts if you don’t do as I say.

On haste

Haste is sexy. As in, crazy sexy cool. As much as we love to see our crit bubbles, the feeling of a Greater Heal flying off your golden hands at light speed is just…awesome.

There is a lot of discussion about the haste cap for discipline. I won’t rehash the numbers, except to say you can easily find plenty of wrong information. The truth is that with 5% haste from gear, your GCD is capped at one second while under the influence of Borrowed Time and normal 25-man raid buffs. See here. The same one second cap applies to the cast time of Flash Heal.

That’s a soft cap. You can stack haste well beyond 5% and get plenty of benefit:

  • Any time you aren’t casting with Borrowed Time up
  • Any time you don’t have a full set of hasty raid buffs
  • Any time you’re casting a Penance, Greater Heal, or Prayer of Healing

These are real possibilities, which is why haste is not hard-capped. Every point of haste always decreases the cast time of Penance, GH, and PoH. So depending on your spell-casting priorities, you may receive tremendous benefit from haste well beyond the 5% soft cap.

Why stack haste? If you’re on full-time tank duty, in a stressed environment (meaning you can’t be raid-shielding to activate BT as much as you might like). You’ll benefit from haste on most of your Flash Heals…any that don’t immediately follow a shield. And (the limb creaks ominously) your Greater Heals will be significantly better. A haste gearset goes very nicely with a Greater Heal build. GH can be a very good spell, despite what we’ve come to believe, especially if you adjust your spec to include Divine Fury and Improved Healing. And with haste on your side, your heals will actually be useful, and not just overheal.

In other words, there is a new style of discipline tank healing – GH plus haste – and it’s on the rise. You may be a GH hater, but leave it open for now. It’s a viable solution to our tank-healing woes.

Problems? Well, even with a lot of haste, we’re not paladins. Your heals still might not land fast enough. And they certainly won’t be big heals either relative to what a pally can put out. But haste will put you back in the HPS game for sure.

On crit

You know about crit. Not much to say here, except to remind you that as of 3.1, Divine Aegis bubbles will stack. You get a maximum cumulative bubble of 10k. Since DA bubbles are 30% of the original heal, you will get 10k protection for every 33k of critical healing you do. (Only crit heals count towards that, of course.) If you’re on tank duty, spamming everything you’ve got, there is no way you’ll keep up with that.

Some quick math, which you’re welcome to skip. Let’s say you’re doing 1000 hps. If your crit rate is 100%, that means you’re healing for 1500 per second, all crit, giving you 450 protection from DA. Scale those numbers however you want; there’s no way that you’ll be overshooting the 10k cap on DA while on a boss. A reasonable number for DA protection per second would be on the order of 1000.

That’s my new benchmark stat, by the way. Divine Aegis protection per second: DAPPS. “Maximize your DAPPS as a disc priest.” Meme it up.

Why stack crit? To boost your DA mitigation, of course. Your DAPPS will scale linearly with your crit rate. More crit also means higher uptime on Inspiration, but that should not be an issue; it will be up nearly 100% for any reasonable values of crit on a spamming tank healer.

A  disc priest’s shields and DA bubbles are the heart and soul of our spec. We are the best mitigators in the game.  It would seem that our unique value to a raid would be in direct proportion to the strength of our mitigation. And there are two ways to increase your mitigation: get more spell power, and get more crit.

Oh, by the way, spell power

Power Word: Shield does not benefit from haste (except via a lower GCD). It does not benefit from crit (except that the glyph’s heal can now crit). It does not benefit from intellect. The only way to increase the size of your shield is to add spell power.

To the degree that shields are part of your rotation, you need to be boosting your spell power. For a long time, it was the only stat I gemmed.  You can’t go wrong stacking spell power.

Of course, spell power helps all of your spells, not just shields.

On intellect

(The sound of snapping wood fills the night air. Guttural growls from the beasts below spark adrenaline rushes of fear. I could still turn back…)

As far as I’m concerned, intellect is a special-purpose stat. Of all the fights in the game, of all the different types of groups and healing teams, there are relatively few that require mana pools bigger than what you get from the gear you receive when you’re playing level-appropriate content.

There, I said it.

If you’re a PhD, you might argue with me, saying that 99% of the fights you’re working on require massive mana pools because of the dps requirements of hard mode Yogg, etc. Great. But if you’re at that level, what are you doing here?

All disc priests love their intellect. Some stack int for the sheer joy of the massive mana pool we get from Mental Strength. Some love to be the last person still healing in long fights. Some like to have a huge insurance policy for when things go horribly awry. And some believe that because intellect is related to crit that in fact it’s not merely a regen stat, but a combo regen+throughput stat.

It’s not. It takes 167 intellect to give you 1% crit. That’s eight epic gems. If you’re trying to get crit rating, do not stack intellect. If you’re using the additional crit benefit of intellect to justify stacking it, you’re deluding yourself.

You should power-on the intellect if and only if you are mana starved. It is a regen stat, and it is our best regen stat without question. If you end fights with half your mana and with shadowfiend off cooldown, you do not need more mana, and therefore you do not need to stack intellect. However, if you’re doing fights that require constant spamming of your biggest heals, and you struggle to last long enough, intellect is the clear choice.

On spirit & mp5

Every time a discipline priest slots a gem with mp5 on it, a new death knight is born.

Every time a disc priest uses more than one purified gem, a rogue starts an arena team.

Every disc priest who uses a spirit trinket (one exception) has secured themselves a dossier and an active case at the Internal Affairs department at Discipline Central Oversight.

If you need mana, get more intellect. Or, for more modest mana boosts, use one of a few solid trinkets that will extend your mana pool more than you probably think. Use a single purified gem to activate your meta. Otherwise, do not justify using any blue-tinted gem with issues of regen or even socket bonuses.

I’m watching you.

My role in 3.2, and its gearing implications

In 3.1, I found my role to be a supportive tank healer and a supportive raid healer. I could be assigned to a tank, but still shield the raid a tremendous amount. This allowed me to keep up Borrowed Time (and my 4-piece bonus). But in 3.2, I’m finding a lot less time for shielding. To make myself useful, I’m leaning heavily in the direction of a major increase in DAPPS. This is something that no other class can do. I could stack haste, but I’ll still never approach the sick amount of healing done by our druids and holy pallies (with whom I share tank duties).

So my gearup plan for 3.2 is a massive buildup of crit first, spellpower and haste second. I will be solidifying my unique role as a mitigator, rather than trying to close the unclosable gap in HPS.

In conclusion

  • Spell power is always good. It boosts your healing spells and your mitigation.
  • Intellect is usually bad. If you need more of it, you’ll know it, but do not listen to anyone trying to tell you it’s the überstat for discipline priests. You should have plenty on your gear already for what you need. Intellect does not add any (significant) throughput; it is purely for longevity, and it excels at its job.
  • Haste is fun and fantastic for burst tank healing. It will improve your throughput and ensure that you run out of mana sooner.
  • Crit will boost mitigation (which we now call DAPPS) and of course your overall HPS.

Next up…

A crit-oriented gearup plan for 3.2. That is, if I survive the fall and evade the lions awaiting below…

Paolo: I need a gem please.

JC: Sure, what kind? We got red, blue, green, you name it. Attack power, intellect, what do you need?

Paolo: Um, this. (Reaches under his Bauble-Woven gown, into his back pocket, sorts thru several crumpled pieces of scrap to find the one he wants, and hands it to the JC.)

JC: (Tilting his head, trying to read what’s on the paper.) Say what?

Paolo: I need a gem.

JC: This isn’t a gem, noob. This is a profile of how you might look someday when you shed your noobish skin a few times. Not today though. Today you can have one gem, which means one stat, two if you ask nicely. But you cannot have “0.3 spellpower, 0.25 intellect, 0.25 crit, 0.1 haste, and 0.1 spirit.”

No, I’m not going to try to convince you that I have better numbers for you to plug into Lootrank. Theorycrafters will do much better than I will at producing stat ratios on the optimal end-game gearset.

And I’m also not trying to compare buying a single gem with designing a plan for your end-game gearset. I was just having fun.

No, this is a little more real-world. When the theorycrafters tell you to weigh crit by 0.25 and haste by 0.15, that doesn’t mean that the next piece of gear you should get must have those stats in that ratio. You meander. The next piece of gear might be all crit. Then the next might be all haste. Etc.

The stats behind the stats, and Disc’s strengths & weaknesses

All of the stats you find on equipment end up translating into one of two fundamental healing abilities:

  • Throughput: the ability to pump out more heals per second (HPS). Aka “hit harder.”
  • Longevity: the ability to heal for longer fights without going out of mana. Aka “last longer.”

That’s pretty much it. Some stats translate in an obvious way: more spellpower, for example, will make you hit harder, while more mp5 will let you last longer. Other stats have a more complex response: crit, for example, gives you more throughput, and some extra longevity as well (via Rapture procs on Divine Aegis). In fact, most stats have some crossover — even spellpower will increase your longevity a bit via its impact on Rapture regen.

Disc’s strength is its longevity. Rapture rocks, and our other mana-saving talents are wonderful as well. Our weakness is throughput. Holy priests hit harder, that’s just the way it is. Both the low throughput and high longevity are inherent properties of the spec.

And as you’ll find when you start playing at 80, you desperately need to address your weaknesses more than you need to advance your strengths.

More on the individual stats

Here are how the stats affect your throughput & longevity. Green is a positive effect, red negative, and the stronger the color, the stronger the effect.

 

Throughput

Longevity

Spellpower

  

Crit

  

Int

  

Haste

  

Spirit

  

Mp5

  

Look at that…only one red cell. Keep that in mind: haste is great for throughput (more heals in a shorter amount of time), but bad for longevity.

The three phases of Disc gearup

Enough chitchat. Here’s the point.

As you gear up, you will go through three phases during which your priorities, and the resulting gear choices, will shift.

Phase One: You just hit 80, and are rocking maybe 1300 spellpower. You simply cannot keep a tank alive through heroic anything, and Patchwerk is your worst nightmare. You need help.

Stack spellpower until it hurts. Regen (either intellect or mp5/spirit will work) is a close second, but gem and enchant for pure spellpower, because throughput is your biggest weakness. Avoid haste at all costs. Take crit any time you can, but do not trade any spellpower options for crit. You will be getting int along the way without particularly trying.

TLDR: Spellpower >> Intellect > MP5/Spirit > Crit

Phase Two: Oddly enough, even though you’ve been focusing on throughput, it’s your longevity that has benefited the most. And you now are feeling confident with longer fights, even if you’re still having difficulty with spike damage.

Start backing off regen items. Continue to stack spellpower, and focus on building up a solid base of crit, aiming for 25-30%. Continue to treat haste like a disease.

TDLR: Spellpower > Crit

Phase Three: Stack haste. Get rid of regen items to the degree that you can. Now you can, if you like, gem for intellect.

TLDR: Haste > Spellpower >> Int

A final note on throughput & longevity

The reason you should focus so aggressively on throughput is because of the huge number of third-party support options for longevity. In other words, here are some buffs that you can get from various classes:

Strong longevity buffs: Pally, Shammy, Mage, Shadow Priest (or ret pally)

Weak longevity buffs: Pally, Druid, Warlock (in the absence of a mage)

 

Strong throughput buffs: Shammy, Druid

Weak throughput buffs: (none)

Hence you must take care of your own throughput.

Example: Glyphs

You of course have Glyph of PWS and Glyph of Flash Heal. If not, please return your disc membership card as you exit the building. But what of your third glyph?

During phase one, it’s an easy call. Renew. Yes, the evil HoT, the anti-disc spell that procs of none of our delicious cookies. Well, the glyph turns your renew into an HPS machine. It will now hit for harder each tick, and you have it up on the tank at all times anyway (don’t you?). Yes, you’ll have to cast it more often. But we’re interested in HPS right now, and the tradeoff we’re making (wasting a GCD more often) is easily worth it.

During phase two and phase three, playstyle choices are more relevant. You can glyph for dispel magic (there’s a ton of it needed in Northrend) or for Holy Nova (another formerly-hated spell, now finding its uses), Prayer of Healing. Your choice.

Example: Cloak

On the assumption that you are willing to dump 800g or so into an epic you won’t replace anytime soon, get a Wispcloak made the day you hit 80. It has as much spellpower as you could hope for, and 20mp5 is crazy for a cloak. If you’re a tailor, put on Darkglow for extra regen.

By the time you hit phase three, you should seriously consider spending another 800g or so to get Deathchill made. The loss of stats, including the regen, is perfectly acceptable at this level. And haste is now something you are seeking, because regen is no longer an urgent issue. And instead of putting on Darkglow, get it hasted.

Talents

At this point you should understand this philosophy well enough to navigate the talent choices you have. How should you relate to Enlightenment? Improved Renew? Improved Divine Spirit? Absolution? Those are a few of your negotiable talents, and based on what we’ve been talking about, they are the ones that will shift around as you gear up. Play around with them as you progress.

Paolo: I need a gem please.

JC: Sure, what kind? We got red, blue, green, you name it. Stamina, defense rating, spirit, what do you need?

Paolo: I just hit 80 bro. What’s the fattest spellpower gem you have?

JC: Excellent choice my friend. Wanna heal H.VH?

So I got me to thinking the other day: why the hell am I in mostly quest blues? Gearing up to entry-level epics has been nothing short of frustrating. I don’t have many heroics I’m interested in running…I’m not badge farming…reputation farming…what gives?

Rewind: The road to 70

Within an hour of hitting level 70, I had eight epics.

That’s right: three BoP primal mooncloth items. Two BoE whitemend items. And I had saved up enough honor for three more PvP epics, including the healing mace, cuffs, and a ring. All enchanted and ready to go.

Snap your fingers, and I went from 69 to uber.

Buying your way to uber

All those level 70 starter epics came without ever having to worry about a random drop. There are four ways to get gear that are non-random:

  • crafted items
  • faction rewards
  • PvP honor gear
  • Badge/emblem gear

Yay Blizzard…giving people ways to work for upgrades that don’t require raiding. And even if you do raid, you can neutralize the sting of the RNG with these purchasable epics.

Stats for discipline

Refresher course: Disc loves crit.

Oh, and mp5 please. We get no bonus from spirit like holy priests, so point for point, mp5 is usually superior, if only by a little. And while Rapture rocks the house, and Replenshment, well, replenishes it, you still need your own regen.

Haste? Sure. After everything else is filled, I won’t reject haste. But it’s last on the list.

Here, my friends, is the perfect discipline item. If I could wear Lattice Chokers all over my body, I would. Until I can get all the items on this list. Unfortunately, most of them require running 25-man raids, which I really don’t enjoy.

Oh, and no, I’m not planning to drop 8k gold on the Signet of the Kirin Tor. If that’s for you, awesome.

Window shopping

Let’s see what non-random upgrade gear we priests can wear, shall we? With one exception, I’ve omitted anything with hit rating.

Signet of Hopeful Light (ring, Argent Crusade exalted). Haste.

See a pattern?

There is exactly one piece of crit gear for healers (Lattice Choker). The Ward of the Violet Citadel, with its points in hit rating, is clearly aimed at dps casters, but I will still probably get it because of the lack of other viable options for that slot.

All I can say is that I hope this list is terribly outdated very quickly.

But for now, I will continue to grind heroics hoping for the right drops. And Naxx of course, but that will be much slower.

This blog was mis-named. It should have been "Divine Aegis Priest," but the marketing folks told me it has no snap. Divine Aegis is, I believe, the defining talent for disc priests. Penance is pretty, not to mention awesome. But DA is awesomer. (And it's pretty too.)

The 30% additional damage mitigation is huge. DPS classes have had various versions of critical strike damage bonus talents (e.g., Ruin for warlocks, and now Shadow Power for spriests). DA acts as our equivalent of a critical heal bonus.

The math is simple, but worth considering. Let's say you have a heal that hits for 1000, crits for 1500. The DA shield adds an addition 30% of that, or 450 mitigation, bringing your net to 1950. This is essentially the same as a 100% critical heal bonus.

Divine Aegis: Increases your critical heal bonus by 100%. Like, omg.

Once I really grokked the power of this talent, I began stacking crit. I bought Xiri's Gift, and Wristguards of Tranquil Thought, stuff no holy priest would be caught dead in. I started wearing shadow gear, like my Corrupted Soulcloth Pantaloons. My crit rating is over 24%, before you start factoring in Renewed Hope, consumables or raid buffs.

Consider: Prayer of Mending - 5 chances to crit. Penance - 3 chances. Prayer of Healing - 5 chances. Flash/GH/Penance - crit chance probably augmented by Renewed Hope. PW:Shield/Flash - you're spamming these, so you're probably critting like crazy with 'em.

(That's a key point btw. Disc priests have become spammers, like pallies. We don't dodge the 5sr as much as holy priests do, at least in my experience, especially now with Rapture. So while you can't rely on crits to do your healing for you, if you really are spamming, and multi-shotting with PoM and Penance, the crits are going to be constant. Still not as reliable as +heal bonuses, but almost!)

Don't get me wrong: all priests will be stacking crit to some degree by level 80. Shadow priests can now crit on Mind Flay, and Shadow Power gives them a 100% critical bonus. Holy priests have Surge of Light (which is awesome now) and of course Holy Concentration.

The theorycrafters will keep us informed once they figure out the right balance of spellpower/haste/crit/regen. And while I listen carefully to the smart guys, I also play by feel, which is perhaps not the min-max-iest way to play. For now, feel is telling me that crit is worth as much as spellpower for a disc priest, at least at my level and for my play style.

Aegis bubbles everywhere! I am a living HMO...prevention is more powerful than the cure.
