I apologize for this week's Build Shop being a day late; I've been driving all around North Carolina and internet access has been spotty. This week we look at the master of fire and shadow, the Warlock. I've got a lock at approximately level 55, so I'd rate my knowledge of the class "medium." This one should be a bit less noobish than last week's Warrior write-up, at any rate.
This build comes courtesy of Rixnor, of Serious Business on Duskwood (H), who "thought [he] would show you a Raiding Demonology build that doesn't get much love." He's tried 0/21/40 and 41/X/X, and likes 0/40/21 better for raiding. He says he "felt gimp" in 0/21/40 due to having to have a pet out all the time, a lot of the Destruction talents not doing much for him (he likes shadow), and aggro limitations. As he rightly points out, pretty much any good caster is putting out as much dps as he can without pulling aggro off the tank, which means anything that reduces threat increases available DPS. One thing I don't know is how much Soulshatter changes this balance, but still, reduced threat is nice.
