Priest – Race Guide from Class Discord

HUMAN

PvE: mediocre, PvP: mediocre
The Human Spirit – 5% bonus to spirit.
Bonus mana regen and healing. May be preferred over Fear Ward in latter PvE content, albeit even some AQ mechanics involve Fear.
Perception – Increased stealth detection for 20 sec every 3 min.
Helpful against rogues, albeit Stoneform’s more reactive nature may find more uses.
Diplomacy – 10% bonus to all reputation gains.
Convenient, but absolutely useless in combat.
Desperate Prayer – Instant heal with no mana cost and 10 min CD. 1384 to 1622, 42.9% coefficient. Cannot be cast in Shadowform.
Desperate Prayer is a nice (save me) button for both PvE and PvP, but it’s not exclusive to humans as it also comes on dorfs.
Feedback – Deals shadow damage and drains mana upon being hit by a direct spell. 33.3% coefficient on R3 (probably 42.9% on R5). R4 and R5 inaccessible on MangOS. Permanently lost on MangOS if you take the lvl 20 quest in Ironforge instead of Stormwind. Only procs on direct damage spells on MangOS.
R5 deals 362 shadow and mana damage at 600 spell power. If properly scripted and proccing at every spell cast against you, it becomes a very solid anti-caster spell (unless dispelled by another priest or shaman). Otherwise, it is only viable against mages. No use in PvE

DORF

PvE: good, PvP: good
Stoneform – Removes and grants immunity to Bleed, Poison and Disease effects, also increases armor by 10%. 8 sec duration, 3 min CD.
Helps a lot against rogues. Useful in AQ and on Chromaggus.
Frost Resistance – 10 frost resistance
Minor advantage in final encounters of Naxxramas.
Desperate Prayer – Instant heal with no mana cost and 10 min CD. 1384 to 1622, 42.9% coefficient. Cannot be cast in Shadowform.
Desperate Prayer is a nice (save me) button for both PvE and PvP. It also comes on humans, but overall Dorfs make a better package apart from certain circumstances.
Fear Ward – Target is immune to next fear effect. Lasts 10 min, 30 sec CD, can only be applied on one target at once.
Sick for PvE and PvP alike. Having this spell will almost guarantee you a raid slot.

NELF

PvE: bad, PvP: mediocre
Shadowmeld – Stealth knockoff, but moving dispels it.
May save you from a random pat if you are too careless. Mildly useful for avoiding PvP action.
Wisp Spirit – 50% more speed in Ghost form.
Quality of life racial. If your guild is bad, you will appreciate it.
Nature Resistance – 10 nature resistance
Minor advantage in AQ.
Starshards – Channeled 6 second damage spell. 30 sec CD.
Pretty much a non-shadow version of Mind Flay with a limiting cooldown.
Elune’s Grace – Reduces ranged damage taken and increases dodge chance by 10% for 15 sec.
Mildly useful against melees. Still, Dwarves have Stoneform and Fear Ward against rogues and warriors respectively.

If you are going alliance, dwarves are your best bet for both PvE and PvE. Humans come somewhat close, but are much more situational and lack Fear Ward, so you may have to sit out for the dragon fights. Night elves are absolute garbage and should be avoided unless you wish to fulfill your sexual fantasies or have a clique of friends that will accept you as you are.

UNDEAD

PvE: mediocre, PvP: very good
Will of the Forsaken – Removes and grants immunity to Fear, Charm and Sleep for 5 sec. 2 min CD.
Pretty much a bonus PvP trinket. One of best racials around. Also useful for dragon encounters.
Cannibalize – 10 sec channeled spell over humanoid or undead corpse. Restores 35% health.
Limited in usefulness, but sometimes provides a quick way to heal up quickly.
Touch of Weakness – Deals minor shadow damage and decreases physical damage done.
Somewhat underwhelming, albeit may proc Blackout. Trolls’ Shadowguard is an upgraded version of this ability.
Devouring Plague – Deals shadow damage over 24 sec and restores health equal to damage done. 3 min CD.
On par with SWP and stacks with it. Costs a ton of mana, so using it together with Inner Focus is advised, especially as both have the same cooldown of 3 min.(bearbeitet)

TROLE

PvE: mediocre, PvP: mediocre
Berserking – 10% casting speed bonus, increases up to 25% the more wounded you are.
Its efficiency is diminished by the fact that you will usually heal yourself with top priority just after tank, but still can come handy.
Beast Slaying – 5% more damage against beasts.
RIP Magmadar.
Hex of Weakness – Minor melee damage dealt and 20% healing taken reduction. Lasts 2 minutes.
Classified as a curse, so can only be removed by a druid or a mage. May be worth chain casting against groups healed by paladins or priests.
Shadowguard – Deals shadow damage when hit. 3 charges.
Wannabe lightning shield that can proc Blackout (27.1% chance for all 3 charges).(bearbeitet)

Horde is not as cookie cutter as Alliance, even with a lesser range of choice. Both Undead and Trolls lack any spectacular racials that would make them shine in PvE. For PvP, Devouring Plague gives much needed single target burst while restoring your own health and Will of the Forsaken is possibly the greatest asset you could have. Trolls sorely miss it, but make this shortcoming up to some extent with 3 charge Shadowguard and Hex of Weakness. Nonetheless, Undead are the state-of-the-art PvP shadow priests
