Brewmasters are perhaps the worse pvp tanks right now. Mistweavers are the worse or tied with priests as the worse healers in arena, there is usually one per rbg group due to the fact that they can throw out crazy aoe heals. Windwalker monks, the least represented dps in arenas right now. No one past 1200 rating takes a WW monk into an rbg. I can tell you how it feels to be stunned as a monk....the same exact feeling it feels to be stunned as any other class.
