I don't know. There was a lock that would hunt my 10 man team down to kill them all by himself while I was leveling. I just couldn't do enough damage in between AoE fears and the damage he was doing. Really annoying when he would teleport too. But after 87 I got my revenge. I will say that warlock's CC's and damage seem out of control. With9 guys beating on him I feel like hes a paladin with bubble and LoH... and he can use both.
