I'm trying to decide what class to roll in 4.0.1. What's more promising in this build, locks or mages? I intend to hit 75ish before cata, and can have one of the two for early heroic gearing. I've played melee so long that it has become boring, and want to change it up. Healing has no place for me :P
Does anyone have a comparison of the two? I will be rolling a worgen of the class I don't choose.
