Best Race for Shadow Priest on Horde (pvp)
WotF: as u said, another trink,though it does have a 30 sec cd, that's a mighty bit shorter than 3 min.
TotG: mine hits for around 10-15k and heals for 100% of that. Which isn't alot, but it is alot considering its a passive racial that is automatic.
Cannibilize: excellent in combat mana/hp regen, especially helpful for shadow, since if we cast more than 2 heals, we're oom. Do note, cannibilize's channel is interrupted by dots, so make sure you're not dotted up before nomming down on the bodies.
Voodoo shuffle isn't noticable but it does help, as priests have pretty poor mobility as it is.
But the real deal is Zerking. Ohh man extra dps cooldowns. The goblin 1% helps all the time, Berzerking helps WHEN YOU NEED THAT HEALER DEAD. (caps for extreme)
Plus they OG
But yes, Alliance have the best priest racials:
Human: 2 trinkets
Nightelf: Meld (meld CC/missile based nukes)
Worgen: Sprint to fear
If you're keen on horde, either undead or goblin are fine, they are both relatively equal in terms of racials, but I will always choose undead personally because of the awesome animations they have.
A priest generally shouldn't have too much of an issue with fears, and by using WotF you make yourself vulnerable to other crowd control effects that you would typically save your trinket for, hence why I believe Goblins to be the superior Horde race for Priests. Rocket Jump allows you to quickly change positions, which is paramount to successful PvP gameplay, and the casting speed bonus is very complimentary to Shadow.
