I'm sorry but you are not understanding how we run boxing mages. The point is to never use AM as we want to do as much dps as possible in the 30 secs that our images last. Using AM will reset your AB stack and kill your dps. I never use AM and have hit 50k dps on each Mage for the 30 sec duration. I'm curious how badly the AB nerf hurt us, but I haven't done any dungeons since 4.2 was launched.
