Apparently no upgrade was given to Destructive Fury and Destructive Cascade AA, so the only damage increase for enchanter is 6% increase to each of the Focus spells. That is a relative downgrade to other classes like my bst who still gets plenty of damage upgrades in other places.
Come on man. Not a bug. Very little was give out in the Archetype/Class aa windows for any class. Pretty much focus tab or bust for casters. You can still see Beta forums and look at all the conversations on caster aas ... and the lack of dev responses. Starting a [Feedback] thread for your dps concerns is what you want to do if you want the devs to consider changing things.
Look on the bright side, next expansion you might get a significant boost to those AAs. one can hope they go EoK AA style and next expansion has a huge chunk!
