I think there should be some kind of benefit or incentive to exiling or killing the defeated boss girls. Currently why would anyone do it? To that point, why even make it an option? Give people a tough choice to make between keeping the girl as a slave with one benefit, or killing them with a potentially better, different benefit, or the middle ground of exile with maybe a lesser combined benefit. I think it would add a bit more depth to the system
Goon was shaking his breasts at you in combat. He's been asked to knock it off
Lol.
