I play different classes, and after some bosses fights, I noticed my (left) hand suffered more from using more keystrokes, depending on the class I was playing. At this moment, I feel I hurt the most playing on my BM hunter (think SV hunter is a tad less hurting), but maybe it's something only in my mind. When I play my shadow priest, I hurt way less...
So I'm asking you guys: do you think certain class/specs requires more abilites/less rest, to achieve maximum output?
