what is the best alliance race for a priest in PVP
most pvp players will choose between Human and Night elf.
EMFH and Shadowmeld, which is more useful in Arena?
EMFH can be another trinket, offering more burst/survival.
Shadowmeld can be used to evade a spell, get out of battle and recover mana.
which do you think is more beneficial? i am totally confused now.
Shadowmeld is worthless and fades from DoT damage, and we all know EVERY class has a DoT so its pointless.
EMFH is good, but shares a cooldown with refresh trinks so go Human and use a normal PvP burst trink and a LFR burst trink, or as far as you can go with raiding to get a good trink.
Personally I would say go for human, the possibility of 2 damage trinkets is always a great bonus on your overall and burst damage.
Night Elf: Shadowmeld is amazing, it's a great tool to avoid cc, like poly, fear, scatter and so on, it does require more skill than any of the other racials, but if used properly it could sometimes score you a kill.
Worgen: Now a days most healers got so many instant casts they keep hiding behind pillars, only to move out for a global. So it could be hard to land a fear. The worgan racial makes it sometimes easier to chase people for a kill, cc or to get away.
There is nothing like a go to race, choose whatever you feel the most fun to play with your character.
