Regeneration de mana pour les pretres - Elistisk jerks

II. Regeneration
WotLK makes yet another sweeping overhaul to the regeneration model. In 2.4, we all became used to the regen formula of:

5 * 0.0093271 * Spirit * Square_root ( Intellect )

which made spirit very valuable, and intellect slightly so. Not only was the coefficient lowered as we leveled to 80 (as expected), but Blizzard made the decision to lower the coefficient yet further in an attempt to remove our ability to 'regen infinitely'. Accordingly, the formula at 80 is:

5 * 0.005575 * Spirit * Square_root ( Intellect )

an overall reduction of ~40%. This actually makes intellect as valuable as spirit overall, due to the Replenishment changes.

Replenishment, a talented ability available to ret paladins, survival hunters, and shadow priests, procs a 15 second buff on up to 10 people that restores 0.25% of their total mana every second for the duration of the buff. If you have 20,000 mana raid-buffed, this works out to 250 Mp5. Taking talents into consideration, a Discipline priest gains 0.237 Mp5 for every point of intellect, while a Holy priest gains 0.206 Mp5. As mentioned above, Holy also gains a percent of crit for every 150 intellect, while Disc gains the same percent for every 132.

Thus: (ignoring gains in mana pool size)
Discipline: 132 intellect = 1% crit, 31.3 Mp5
Holy: 150 intellect = 1% crit, 30.9 Mp5

Comparatively:
Discipline: 132 spirit = 40 Mp5
Holy: 150 spirit = 46 Mp5 + 43 spellpower

So obviously spirit is still comparable to intellect in a 1:1 comparison of pure regen, ignoring the regen gains available through crit. However, the gap is much, much smaller than it once was, and there is nothing wrong with stacking intellect and spirit in equal amounts as you gear up. My eventual ballpark is to have 1200 intellect and 1400 spirit, a reasonable increase from Sunwell, where I ran 700 intellect and 930 spirit.

See the end of this post (Section X b.) for a discussion of how much regen intellect actually works out to be. The combination of mana pool size, shadowfiend mana returns, and intellect to crit conversions ends up making intellect stronger 1:1 for regen than spirit. The throughput gains (for Holy) aren't as high, but for Disc, there's little-to-no reason to stack spirit or even care about spirit at all.

Q: How do I take advantage of OO5SR regen?
A: If you are Discipline, you probably don't want to. Disc doesn't have as many 'big heals' as Holy, due to the scaling nature of Spiritual Healing and Empowered Healing, so you are more likely to be casting often. Additionally, keeping Grace up requires casting a spell every 8 seconds at maximum, so getting an OO5SR tick will be a rare thing. This contributes to the rationale that Disc priests should avoid stacking spirit to the extent that Holy priests will.

If you are holy, use Inner Focus, IHC, and Surge of Light to easily 'cheat' the 5SR. Stacking spirit makes more sense in this case, especially since Spiritual Guidance is still a powerful scaling factor.

III. Cheating the 5 Second Rule
Priest OO5SR regen is all about cheating the 5 second rule. Blizzard's 5 second rule is currently set so that upon completion of a spell which costs mana (the critical factor), you enter a 5 second period (I5SR) where you regenerate mana at a reduced rate. This rate is dependent on your talent choices (Meditation = 30% regen I5SR), but every priest will have this, so it's a moot point.

Given that priests gain so much regeneration from spirit, the typical difference between a regen tick I5SR and OO5SR is approximately 2x. It can range from 2x on the low-end (Mp5-heavy gear) to 3x on the high-end (spirit-heavy gear). In any case, a tick OO5SR is worth a minimum of 2x I5SR.

So how do we cheat the rule?

Firstly, Inner Focus is a guaranteed way to exit the 5SR, since it makes your next cast "free" of mana, and hence does not trigger the rule. Typical sequence is something like:

* top up your tank target
* wait 2 seconds
* hit Inner Focus
* start /stopcasting GH:9 until heal is actually needed
* start a new heal -- when it lands, you re-enter the 5SR


You can do exactly the same thing with Improved Holy Concentration, which should be somewhat easy to do given that ~ 1/11 casts will proc IHC now. Stopcasting is still valuable in WotLK!


There are a couple of useful trinkets that help contribute to this type of play. One is the old-but-good [Earring of Soulful Meditation], which is unfortunately eclipsed in WotLK by the lack of spellpower. However, there is a direct replacement, available from Gothik in Naxx.10, called [Spirit-World Glass].

V b. Taking Advantage of Shadowfiend:
If you've played priest for long, you've learned to hate our stupid mana regen pets. They're slow, they randomly attack the stupidest things, and they generally return a variable amount of mana that is undependable. Despite this, they're the only game in town, so we're stuck with them.

If you are using your shadowfiend in an environment which has constant AE damage (example: Felmyst), you may want to macro in a /target Shadowfiend, /cast Power Word: Shield, as the shield, while costing mana, can often save the life of your Shadowfiend and restore 2-3 more ticks of mana to you.

Note that the shadowfiend mechanic has been changed in WotLK to restore a set percentage (4%) of your total mana per hit. This means your theoretical restored mana from a shadowfiend is ~ 40%. Since the fiend is affected by Windfury Totem, you will actually get ~ 12 hits, but with a typical miss percentage. Checking logs, so far it appears that 11 to 14 hits is completely reasonable, so anywhere from a low of 40% to a high of 60%.

IV. Downranking and Spell Coefficients
Q: Is downranking spells still viable?
A: Nope. Nonexistant. It's done. Dead. Finished. Kaput.

Blizzard changed mana costs of all downranked spells to be the same as the maximum rank. There is no reason whatsoever to use anything but max-rank of every spell you have. This helps slightly with bar bloat, and hurts tremendously in our granularity of heals.

Thanks Dude ! That's all i need!

héhé I know, maybe i'll do a translation if i have time

Miam, merci Zak

II. Régénération

WotLK connait de nouveau un changement important sur le calcul de la régénération. A la 2.4, nous étions tous habitués à la formule :

5 * 0.0093271 * Esprit * Racine Carrée (Intelligence)

L'esprit était très important, sans oublier un peu d'intel. Non seulement les coefficients ont été abaissés au lvl 80, mais Blizzard a décidé de descendre encore plus ces coefficients dans le but de limiter notre capacité de "regen permanente". En conséquence, la formule au lvl 80 est :

5 * 0.005575 * Esprit * Racine Carrée (Intelligence)

Un taux de réduction d'environ 40%, ce qui rend l'intel presque aussi importante que l'esprit, à cause des changements de "Requinquage".

Requinquage, une capacité disponible pour les paladins spé vindicte, les chassous spé survie, et les prêtres spé ombre, un proc de 15sec qui buff 10 joueurs et leur restaure 0.25% du mana total par seconde. Si vous avez 20.000 points de mana (buffé en raid !), ça vous rendra 250mana / s.
En prenant les talents en considération :

Discipline = 0,237mana/s pour 1point d'intel
Sacré = 0.206mana/s pour 1point d'intel

Comparaison (entre intel et esprit) :
Discipline = 132 intel = 1%crit + 31,2 mana/s
Sacré = 150 intel = 1%crit + 30,9 mana/s

Discipline = 132 esprit = 40 mana/s
Sacré = 150 esprit = 46 mana/s + 43 puissance des sorts

Il est donc évident que l'esprit et l'intel ont toujours un léger écart au niveau de la regen pure, et si on ignore la regen mana lors d'un critique. Cependant cet écart est beaucoup plus petit qu'avant, et il n'y a rien d'incorrect à monter l'esprit et l'intel à égalité. Mon but personnel est d'obtenir 1200intel et 1400esprit, une augmentation sympathique depuis Sunwell, où je tournais autour de 700intel et 930esprit.
