Heh, when you think about it, backstab is actually a dagger mastery for the Survivor class that only works 50% of the time (except for the fact that backstab does double dmg instead of +50%). And on top of that, you don't have the choice of backstabbing with a 2 handed weapon. Talk about short changing the dagger wielders... It's gonna take a long time to kill anything in hard mode. I would have to put points into every melee enhancing skill there is.
