I just can't bind all of them. I have no problem with 5 buttons Furry spec, but Arms, omg, how do you bind all of your abilities? I am not good at using buttons from nmb. 5 - 9 and F5 - F10. They are too far away from my fingers, so i am forced to take more passive talents which i don't like too.
I use 5 mouse buttons, regular numbers from 1 to 5 and q,e,r,t,v,b,c,f. Sometimes i bind F buttons from f1 to f4, but it's hard to play a melee class with F buttons, it's way easier to do it with range class.
Ability pruning my ass.
