Also I think there are some ballance issues. Suki and Natasha are basically useless in party. Four of the girls each have their own speciality, and Esxea is a multitask generic aoe girl. But unlike the others, Suki's pussy stats are too low, even lower than Esxea's stats at the same level, so I could just use Esxea for a "front job". I mean, you could rise Suki's pussy stats a little, so it will be equal to Queen's throat, for example.
As for Natasha, her stats are just too low, as expected, but in return she should have impressive magic skills, maybe even applicable to the whole party. But she doesn't have it. The only purpose of her skills is to temporarily increase her own low stats, so why use her in the first place? I just think that her magic skills should be reworked and improved. Hope I didn't upset you ;)
