Everyone says paladin is the worst pvp healer right now? I can't even dent one in full prideful. They just use one spell and they back to full again. Ok yeah I use interrupt and stun but they only need one or two seconds to heal back up. Mana bar doesn't even move.
Shaman is said to be the best. I try it but I can't keep myself up if I have a warrior or rogue on my behind. Ranged aren't too much of an issue.
