Given that the math/algorithm for stocking equipment is messed up and that the legendary items purchased with kobans have incorrect stats, it isn't a far leap to think that the math for the harem members is incorrect as well. I've raised Donatien from level 45 to 60 through battles with him and I had A LOT of battles logged beforehand. I'm hoping that the drop isn't completed busted and that at least a few people have been able to get girls at all.
We STILL haven't been told what happens to the rate increase that we're given on successful fights after we get a girl. Excuse me, if we get a girl. Does the win reset the rate to its base rate again or does it stay at the same level to keep increasing?
