I realize not many people here still play, but if you still have a copy, patch 2.0 was just released. The big changes include:
-Move support
-revamped skill tree and new in-game economy
-max level has been upped to 70
I believe there are changes to some of the larger maps in Acquisition and Domination as well as other gameplay tweaks.
