I think it's fair to say at this point that it is unrealistic to expect Larian to change their toilet chain system. They have not once addressed the feedback so I can only assume they have noticed it and chosen to ignore it; whether because they are adamant it's fantastic, or whether it's because of multiplayer or because there are limitations in their engine...I don't know. Anyway, I can only hazard a guess, from my own ignorance of software development, that rewriting the party control system is something they do not want to sink resources into.
