The best part is where they said "listening to your feedback" ROTFLSHMSFOAIDMT.

Players wanted a safety net to avoid wasting kobans and they fucked up the drop rate, so that you need years to get a girl, instead of a maximum and reasonable number of battles.

OK, the previous system was totally crap, but this one is the same in its own way.

As always, stopping wasting money in games like this is the best choice ever.
