I almost feel disinclined to play as a Barbarian now. The hidden stamina and heath bars will make me a little too nervous to put my character avatar in the front lines, very much vulnerable to death and a subsequent game over (assuming that Ironman is enabled). Maybe hide the Stamina bar but not the Health bar? It would make thematic sense - the Barbarian can't distinguish minor wounds while Frenzying, but deeper wounds still register. In any case, I'm looking forward to the Fighter, but Chanter, Cipher, and Monk seem so damned cool to play. I can't wait to see how it plays out.
Also, to those bitching about beta access and footage - why? The release is getting closer, but it's still six months away. This is a game that's going to be heavily plotted; unless all you want is a combat sandbox, I don't know what you expect Obsidian to deliver at this point, and I'm not really interested in playing Eternity for the combat anyway.
