And it's about hitting maximum potential damage; a 3-hit WS like Raging Rush only needs >80% acc to land all 3 hits (hitting the maximum potential) >50% of the time, while Asuran needs >92% acc to land all hits >50% of the time. Yes, missing a hit on RR is a bigger chunk of damage lost than missing a hit of Asuran, and the general goal should be to get acc as high as you can without making any significant sacrifices to attack/WSC for either WS, but Asuran needs a lot more acc to reach a certain level of consistency than other WSes do.
