I have about 640 AA atm. I don't earn them very fast because when I'm on I'm usually raiding.

My question is... should I get the DoDh AA before some of the DoN or older AA's I don't have?

GoM3, Shared Camo... get em ASAP.

If your magelo is accurate, get Quickened Curing and Resplendant Cure as fast as possible since you raid. Consider maxing out SotG. Affliction Mastery is a nice one to have after.

I would recommend Abundant Healing, but I'm not 100% sure if its fixed. So for now... wait until you get those others.

I just purchased GoM2 and updated magelo.
