My problem with the upgrading is that I'm literally getting girls faster than I can upgrade them. I'm not sending a dime either. I was close to catching up then this new update tanked it. Now I'm way behind again. I haven't started trying to get girls to 5 star because I have a bunch of 3 stars left. It's more beneficial to max them out first, but I can't catch up.

Basically you get 2 weeks a month of lull to grind before getting new girls in an event. The events kill the cash flow because you have to fight low bosses to get the event girls. Maybe at max level it will be better, but it will take weeks to max them out and then get back the money lost. Finalmecia starts at half what she was paying. It discourages me from playing when I feel like it's going to be impossible to ever catch up. I realize I'm still making progress because I am maxing out girls which gives me more money, but I hate that endless grind feeling.
