Hello Fighter's roll. Which puts you 80-90% depending on gear choices.
Last I checked 80-90 is less than 100.
(On a more serious note, I suspect that with that set you're reducing your damage compared to 60% DA with more crit dmg. But I do not have the data to back this statement, nor the ability to spreadsheet it out right now.)
Also if you're zerging, Brazen Rush is a thing.
Very true, but still not the reason MS Reso is so strong. Besides, if you have MS+Brazen Rush on, it's best to forego all DA from your WS set, and go full STR+crit dmg.
