As I don't have access to the Beta I haven't been able to really get a feel for how the attacks work in practice.
My question is when you use skills & affixes to increase your weapon attack speed to multiple times a sec do you need to mash the mouse key or is it handled better than that? Can you attack once and keep the key depressed?
I was thinking specifically about making a frenzy barb and using two very quick 1-handers with as much + attack speed buffs. If its going to be RSI hell I might think again though.
