no, maxed reduced hayate usually doesn't cut it because his base attack is 160 at max level. I'd say go for saki after getting spica or AW spica, and maybe after AW'ing 3~4 units that you feel are useful. atm I have AW'd bernice, spica and katie, and my next AW is most likely saki due to AW fodder issues (no healer fodders). with nutaku's event pace, silvers are a highly limiting factor in AW.
