So I've decided that though Event girls are better in the short run, Gacha would be more useful in the long run because I would eventually come across dupes while doing it. Also as Volarmis reminded me Whale mission exist. I was only thinking about getting a solid team of 20, and forgot I needed more for Whale. But here are my responses to each reply I hadnt gotten to yet.

I didn't account for abilities in my calculations. I do agree that abilites are needed and that some Event 5*'s abilities suck. Thank you for the information, I'll look more into abilities of both event and Gacha Girls


Volarmis
I completely forgot about the whale honestly. And Gacha is the best way to get to doing whales sooner. Thank you for bringing this to my attention.

I can't agree that gacha 5*s are "stronger" than Event girls. I mean, yes, if you disregard the fact that event girls have 4 slots and lv.5 skills, then a Max level gacha 5* 1 slot lv.1 skill would be stronger by pure base stats.

Hello and welcome, be it a guest or someone that just decided not to log in.
Taking in account that each new girl can give 3FG's because of 2nd affection, I can see how this system can be quite useful.
