@Coin I wasn’t going to go that far, but since you went there, I will say that I think if the game is designed around it and everyone is onboard, and it’s specifically designed to avoid “I roll to get in your pants,” then I think social skills have a great place in a MU* (I would have a hell of a fun time with an FS3 Regency MU* with a social combat system instead of a physical combat system, for instance).
But if the game isn’t designed with all that in mind, I think it’s best to keep it to rolling vs NPCs only.
