I love my warlock. Top damage nearly every BG only some 24s and rarely a 20 hunter can out dps a lock. Super easy to gear took only a couple days to level and get dungeon gear. Started mine the week of WSG weekend and had 3 boas (nearly 4) by the end of the weekend.

I like affliction spec the best. Still good burst with fear/SF/insta SF. And 600 Bane of Doom ticks are straight lawlz. Great CC with fear, and decent survivability/mitigation. Excellent healing with drain life/ soulstone/ harvest. Never run outta mana. And if you like seeing big damage locks are pure sickness. Done 80-90K damage in WSG, more then I ever did with my huntard.
