Yeah, Warlocks are pretty silly.
Came across one with 3700 spell power buffed. I have 42k health in Bear form when buffed (same buffs) and thanks to talents I get 6% less chance of being crit and take 12% less damage from everything. This Warlock killed me in one Fear. Basically Immolate, Conflagrate, Chaos Bolt, Incinerate, Conflagrate and I was dead. Fear did break after the Incinerate, but due to the daze crap, I never even got near him.
My Warlock is so going to be a PvP monster when he grows up.
