I remember back when the game launched, I was able to get most of the girls from the first two maps. After waiting for the mushroom kingdom, the amount I played reduced. However since two weeks before the release of the kingdom until now, going through multiple maps I haven't gotten a single girl. In the sense of stamina, I feel I have used at least 6000 stamina without getting a single girl.
Please at least increase the maximum amount of battles so that at least we can battle more if you're keeping the rates so low. Otherwise people start losing interest in the game once there aren't any events if you battle for days straight without getting anything at all.
