more quickly the skills, less reuse. but the bonuses are % (7 % give AS + Haste , that mean ur atk speed + (ur atkspeed / 100 x 7 ) = this mean if u got more atk speed the SA will give u more too. this why on HR servers were u got 50 /60 ... buff slot all use AS + Haste , and on Low Rates with less atk speed because of 24 buff slots limit, most of ppl use AS + crit dmg even if give a fixed 265 dmg on a critical attack , but even here u got vicious stance, death whisper that give % crit dmg so ... more basic dmg wen u give a critical = more dmg on final dmg.
