Ash, what do you think of Archetype's suggestion here:
I think its balanced. At least, for real life Mafia. If you want more roles, I think 3 Vanilla Townies/Town Cop/Town Doc/Mafia Roleblocker/Mafia Godfather could work well IRL.
It mitigates the Doctor/Cop brokenness by including a roleblocker. It looks fun to me. The main difference is trading the in-the-spotlight pressure on the IC for the behind-the-scenes pressure on the doctor. Probably both are good, and I think that hiding the roles on the flip prevent the doctor from being OP in both scenarios.
I agree that it would be fine, balance-wise.
I guess it depends on what you are looking to get out of the game. It's IRL, it's with real people that you know. Are they going to prefer the focus on daytime scum hunting more, or will they like the night action results stuff? The more roles you include, the more people focus on nights and claims.
And that's cool, but it needs to be what you want.
