Feldon Aeralik has chimed in with the first hints of what we can expect in GU52:
GU52 has a wide variety of things coming. From what I understand there will be an assortment of new quests and additional content which means additional ways to raise your aa points if you havent yet. You have to keep in mind dfferent people have different responsibilities. My job is to work on the class balance and combat systems which this falls under and like I said is the first part of a greater plan which we will talk about more in the future. While I am working on this and some other things, the other projects do not suffer at all and actually its actually pretty amazing how much stuff is going into this next update.
