if this thread is pointed to any healer type, i can say spirit is useless for pvp because paladin does not require spirit and they need crit and mp5 instead of spirit so i'm kinda agree with quazacolt, pvp does not require spirit instead of mp5.

btw my paladin go for crit instead of mp5 in pvp actually lol cause FOL and holy shock crit save 1 heal.

example:
normal FOL is 1.5k and if crit can go up 3k = 2 heal saved 1.5sec casting
