It looks to be a pretty big update and the new undead art looks like a huge improvement over the old stuff. A lot of good changes/advances going on with this game.

I forgot to mention, I remember seeing a few comments from people about how they tried returning to AC but not having modern MMO controls bugged them.

A few months back they added mouse turning so now you can have a control setup just like all the other MMOs out there.
