It's always great when events roll around I save my kobans for weeks and I always find myself spending all of them refilling my battle energy because the girls never drop. I battled ninja master HUNDREDS of times and she did not drop, over 5000 kobans in refilling, either fix this mess you call your loot system or i'm going to quit this game which I really don't want to do because i've always enjoyed thjis game up to this most recent update changing the battle system and fundamentally ruining this game for me every single time the events roll around. Please fix or I uninstall.
