4 star requires additional 700, thats 3 times 150 + 250 going by your idea XD.
Assuming the math is correct then affection points needed and thus cost of acquiring them is basically also multiplication, so getting to 5 star is 50 times more expensive on 50th girl overall, no need to exclude affection items needed to use.
I suspect the guy included affection cost, cause upgrade alone was below 800k IIRC.
I already wrote a huge post about it, and then a summarizing post about it. In simple terms:
- Starting 4 girls got their cash per collect up. 2 of them got their timers actually increased on 4/5*, other 2 on 3* got it smaller. Overall cash/h gone up.
- Princess Agate also got her cash per collect and cash/h up, and timer between collects down.
- All other story girls (troll drops and story drops) got their cash/h drop down at most by 30%. Their timers between collect gone down, and cash per collect actually in most cases also gone down.
- All event or epic pachinko girls got their cash/h increased even close to 2.5 times. Cash per collect gone up, time between collects mostly down.
So summing up you get on average less money per collect, thats why your full harem collecting dropped down. But times between collecting also dropped and they did far more than the cash sums being collected. So even if your full harem collect gone down, your cash/h from harem has probably gone up assuming efficient collecting.
What they did is, they made harem require far more busy-work to get good cash/h, which for people that log and collect once per while means less cash/h than before.
You know, I think that I more of less know what was going in their heads when they worked on this update. People whined that girls drop to slow, that getting them is to hard. So they increased their drops, but also gave us free kobans on daily missions being all done each day. Cause of this getting all girls from story and events will be far easier, and also with just kobans from daily missions we will be able to get a single pachinko girl each 36 days, so with some other bonus kobans here and there - probably as often as we get events.
Thus their only source of income from premium currency is collecting money in harem (thats why harem cash per collect/timers got so fucked up), from restoring shop (thats why you need such a shit large number of items and why refreshing cost more than before), and from upgrading the affection stars (thats why they gone for the slopped rising costs), theres still the buy girls via epic pachinko if one wanted to get all event girls on each event.
So in overall things look at first go far easier to F2P, but the moment you see how expensive affections are, it will be the moment you probably will start considering this game being dropped. I could harbor a guess that they moved premium content from girls themselves to affection scenes. Cause now it will be harder to upgrade affection, rather than get the girls.
What I plan to do is to wait till I get the Kalisa from story (or what ever was her name). Then for next event to see if we will still get a nice kobans on event dailies. The girls will let me judge how fucking expensive the affection is, and probably not upgrade it if its the analyzed multiplication or worse. Afterwards I will just wait for some signal from the Devs, if they collected our feedback in email or this forum, and if they are actually planning to make a fast big re-balance update 3.0. If they will fix PvP, completely broken stats balance that we have now, and change affection to a maybe high but mostly static one not the slopped up we have to punish players who play longer more and more the longer they play. The judgment will be based on how long it will take them to response, on what the response is, and the verdict will be if I will ditch this game or continue to play for just story (aka doing nothing else part it), as personally I don't believe in them to much o.0 (so I assume they will respond negatively, maybe changing few small unimportant stuff, or don't answer at all and consider asking us to write mails to them their already said answer).
EDIT:
It seems we got event already, so I will probably get event girls faster than I mange to progress basically last story quest to get Kalisa. The trolls with event girls are Dark Lord and Edwarda.
