Indeed, with proper Alter Time usage Mage burst goes from being good to being great. The only thing that can be a littlebit frustrating is not getting 2 AM procs before hitting 6 stacks so that you have to fish for procs at 6 stacks while watching trinket procs fade away. When it lines up it's very nice though. Hit 300k+ burst on single target quite a few times with stars have aligned in our wee 10 man. ^^"
