So, apparently over at the Diablo Fans forums there was a question about how Fury is going to work for the barbarian class. While the system is obviously still in development and subject to change, a Blizzard rep answered a few questions on the subject (actually they answered more than a few). Read the thread here.
This came out a while ago, but if you haven’t seen it, its totally worth the watch. It shows off how awesome the barbarian is, some of the cool gear, not to mention some of the more 3d elements of Diablo 3. It also has some nice developer commentary.
