I'm leveling my fury warrior (currenlty 75) and plan on trying 2 priests + warrior in PvP. Although I'll also try my 4 priest team, I've missed my warrior (old main before multiboxing) and think that if I concentrate most of my focus on playing the warrior to the fullest then the two priests will work well for easy healing. The nice part is I'll only be taking up three spots in the BG and, as we all know, a warrior with healers is probably the most dangerous thing in WoW.
