If its the focus of the game, perhaps it should be more attainable. My max is six battles, but these battles take 2. It takes an hour to get back. So I can do six battles an hour to try to get a girl that doesn't come or do 12 battles an hour, get more xps and actually get mojo, and collect more money that way. The only bonus I get is they sometimes will drop off items I can sell or more rarely actually use. I can take a certain amount of patience, but why am I banging my head against the wall when I am helped more by doing other battles? I've had literally hundreds of attempts and come up empty.
