I have tried creating a new barbarian and used a barbarian from a saved game. The Barbarian simply does not enter Frenzy during combat. Is anybody else having this issue? It seems like a global problem.
I also can't use barbarian frenzy in 2.01. I was able to revert back to 2.0 (non-Beta) so Frenzy worked correctly. But recently the game updated back to 2.01 even though I had the opt out of beta contact selected.
