@tim myth: after having noticed the loss of hp by wearing a shield tried my axe too and my stats were exactly like you described them. so i looked at my talents and realized that i didn't have any points in my two-handed talent. i don't think of the situation you described as a bug but a simple fault of ourselves in placing our talents the way it is expected for axes :)
also it would be nice to add some more abilities to use for the warrior, only the slow but powerfull regular attack, the blood strike every 12sec and sometimes a rare execute procc are not able to compare with a frost/fire hybrid mage or a rogue
last boss is very easy as a mage with arcane skill: use arcane pulse on the gate till the boss appears so that the monsters can't catch you. then cast natures grasp on the boss and kite him with blinkstep and arcane pulse. it was the easiest fiht of the whole game ;)
