Indeed but rerolling isn't easy too by the time hanuman comes he has missed wind union event also it takes maybe a month from now so don't really sure he want to wait that long. As rare as hanuman, flb weapon also very rare and furthermore wind weapon also give best flb because give you 2 exceed weapons on top of assault large or pride. To get flb is very rare too and he will get several sr assault to help him boost his grid much faster too. He can wait but but is it really worth to wait and reroll again for spesific eidolon. He mostly dont get the 100% eidolon when reroll there is no guarantee even with rate up. In one year of time nothing can be predicted is it close down or have no motivation anymore to play. If he wait hanuman he will lose 2 flb exceed weapons and must do crazy reroll again and collect more weapons. If he use current hraes he can play now, get 2 flb weapons and get many sr to fill its grid faster and hraes active also strong. Its not bad trade off.
