So it's either sub to all characters, or dom to all characters, why not make it seperate, and base which route you're going to be on on the choices you make with that character, that way you can be dominant with some characters, but submissive with others, basing it all of the sub/dom stats is not a good idea, that would make choices not make any sense and completely pointless, those should only play into stuff after you select the route you want to be on (except for some flavor scenes like we already have), maybe they should unlock/lock choices instead, and you can increase sub or dom points in your room (outside of cheating), and have it be possible to become dominant while on the sub path by unlocking dominant choices, same for becoming submissive while on the dom path by unlocking submissive choices, that's how you can branch each route into new, and completely different routes.
