I went with boomkin and Ive been mostly dissapointed. If I had the choice again Id go for warlock. My boomkin is my main and he is fully equipped in ilvl 245 gear. His dps is only just on par with my shamans (all ilvl 232) on bosses but behind on trash. All chars do 6-7k dps on target dummy but Im fairly sure that a lock in ilvl 232 gear would do the same
