I saw a friend playing Destruction on his Warlock and realized that it is nearly IDENTICAL to the Destruction spec we all knew and loved back in Wrath. The rotation is a slight bit different but much of the mechanics are the same. I decided to take my Affli warlock out of retirement and give it a go:

I don't main warlock at all, but this is definitely going to be one of my most played alts. Partner yourself with a healer and a class that can peel/stun for you, and you've got some sweet numbers ahead of you.
