Jov sez: Priests: Regen and YouDecember 2, 2008
Stats: Joveta, lv 75 Holy Priest, currently specced 14/47/5 for questing, STILL getting shunted to DPSing instances (wtf healer shortage?? Where?!) and occasional heal-pwning. Due to the Thanksgiving holiday with the in-laws, almost no time was spent this week on leveling. The only major accomplishment was finally finishing up Tars’ Netherwing Rep, enabling him to have a shiny dragon, too. Go Tars!
I’m not continuing my “everything” posts this week, as I’m fully aware that I’m now approaching the minority to have not at least crested the Cold-Weather Flying benchmark, and raiding is regularly happening. I’m posting this now to try and get information together and out there. None of this originated with me, and I am providing links to all of my sources. It’s pretty safe to say that most of it comes from EJ, however.
Please note: when I say Discipline Spec, I’m assuming a talent spec containing at least 51 points in Discipline; likewise for Holy.
In Which Jov Eats Crow
Regen ain’t what it used to be, and straight mp5 isn’t necessarily the devil. There comes a time in a priest’s life where they may find themselves taking mp5 over spirit. This is not a bad thing. Especially since deep-Discipline is raid-viable, mp5 can seriously outweigh the benefits of Spirit. Quoting from the WotLK Healing Compendium on EJ,
For holy, 9 spirit = 4 Mp5, ignoring spellpower gains entirely. Given spellpower gains, a 2:1 ratio is acceptable.
For disc, 5 spirit = 2 Mp5, with no spellpower gains. Convert cleanly, and make your decision.
What does that mean to you, Mr. Non-Mathcrafting Healing Priest? Essentially, Spirit is twice as important to a Holy-specced priest than it is to one who is specced Discipline, and most of that is due to the bonus Holy gets to spellpower. If you’re weighing the regen between an item with 20 spirit or 12 mp5, Discipline will do better with the straight mp5. Use the weights above, and take the item that nets you more regen.
I feel so dirty typing that.
Also, spirit has been nerfed. The old spirit based regen figures were
5 * 0.0093271 * Spirit * Square_root ( Intellect )
But now we’re looking at
5 * 0.005575 * Spirit * Square_root ( Intellect )
Which means that generally speaking, we’re getting less regen in general. Ghostcrawler has earned the enmity of the spirit-based healers at large with the following response:
As a few players have referenced, we thought mana regen got to a point at the end of BC where players could just generally ignore it and assumed that mana was just a system you eventually graduate out of (kind of like experience).
We don’t want you to be out of mana constantly, but we do want the risk of that to exist. We balance some spells based on their mana cost for example and when you can always use your most expensive, least efficient spell without consequence, then your cheap and efficient spells don’t compete.
Mana is a resource to be managed, much like health or cooldowns.
Basically, we’re not supposed to be never-ending founts of infinite mana and never were. The removal of downranking and the nerf to spirit-based regen was done to reflect that. To Ghostcrawler (on this and other things) I say thbbbt.
Intellect is a Regen Stat
Um, it is now. Thanks to Replenishment and our new reliance on crit, Priests want Int. Yay Int!
Thus: (ignoring gains in mana pool size)
Discipline: 132 intellect = 1% crit, 31.3 Mp5
Holy: 150 intellect = 1% crit, 30.9 Mp5
Discipline: 132 spirit = 40 Mp5
Holy: 150 spirit = 46 Mp5 + 43 spellpower
Replenishment is a nifty tool. Living in the days of “Base Mana” everywhere, it’s really nice to face something that’s based on maximum mana. Essentially, if you’ve got a Ret Pally, a Survival Hunter, or a Shadow Priest, you’re getting the Replenishment buff. It’s a 15 second buff which gives you 0.25% of your maximum mana back per second. How much is that? Well, it depends entirely on how much mana you can get for yourself. You get more regen the more mana you have, so buff up! (And yes, Discipline Priests have an advantage here with Mental Strength.)
Crit is also interesting. Current theory holds that 20-25% is the “magic number” to aim for when getting crit rating. It’s not a direct regen stat, but it snags you time Oo5SR through Surge of Light and Holy Concentration procs. Why 20-25%? That’s 1 cast in 4-5. Put simply, with that much crit, you’re looking at potentially one Surge of Light proc per tap of CoH. Needless to say, that’s pretty snacky.
Intellect vs Spirit
So with the addition of Replenishment, and the fact that Spirit isn’t so OP, you may be thinking to start stacking Int for all your regen needs. If you are, stop right there! Zusterke from PlusHeal (all my healing readers also read Plus Heal, right? Right?!) made an awesome post outlining exactly why you should not be focusing on one stat and ignoring all the others. For the healcraft-averse, the TL;DR can be summed up as: Don’t stack! You want a 1:1 ratio between Int and Spirit! That applies to any spirit-based healing class: Trees, Discipline, or Holy.
EDIT 12/3 : Zusterke has published a tool to let you calculate exactly how much regen an upgrade/consumeable/anything else will net you. Available at Zusterke’s Corner: where undead test their brains…
So to sum up:
- Spirit isn’t what it used to be. Dependent on spec, you may find mp5 is better.
- Smart Priests choose Int!
- But not too much, you’re aiming at a 1:1 ratio between Intellect and Spirit for best regen.
