Most of you have forgotten one thing, you now have two sources of income, harem and boss/pvp battles.
I farm Ninja Spy atm for last girl. Before - 200 cash income per fight, now - around 4500. That's a lot, plus I have 15 battle points instead of 8. And higher level bosses give more money (e.g Edwarda 8000+).

Improving the level of affection costs much more, but for me it's ok (It was too easy before patch). If someone spent one month farming a single girl, affection costs it's not a big deal for him .

Regards.
