I almost agree with op, except that the only problem is rogues because they can gank you and they never ever die. they just vanish and burst of speed away. every other class I can kill because they can't escape, but rogues are just painful in world pvp.
Most censers don't fuck with me because I'm on heroic gear and normally have 1m hp + all the buffs when i'm on the island so it doesn't affect me that much
