All throughout MOP i couldn't stand affliction. I've recently taken a gander at it due to the high mobility encounters in WoD. I have found that I am doing more single target dps in affliction than i was in Destruction. It might be worth it to take a look at it and try it yourselves. I really think the damage while moving will be much better for the upcoming Highmaul raid. Try it out and tell me what you guys think.
