Been playing the Nutaku version for a while now the new prize machine that pops up on returning events is more so you can get easier legendary armor to which helps you win more battles in the tower of fame giving more coins, cash, and extra battle fists prizes. As far as the new system if you havent got any of the girls in a world that you can get aff for any of them at random so you can have something like me with Karole's girls 15, 8, 8 and thats after getting her to 247, however the new legendary seems to be doing better for me as I'm at 25 from 57 battles which isnt bad if it stays at that pace but then again I missed completely on epic days when focusing on Bass and missed female link. I really dont want to miss this legend as they kind of are the most important girls if they match your class as the only build that works in this game is all in on your class stat.
