If hitting traitor, they have to be good, but it's still good (many traitors are just bad, so it's not a big deal). Hitting lm n1 is way worse, but also quite unlikely. Also, IF (but it's even more unlikely, of course) caroler or journ or sw visits lm too, n1, they are not confirmed. This setup is CLOSE to perfect. (I didn't help Kinka in making it, maybe it could seem by my comment :P) I LOVE IT
It's a 9 player setup gist. That means d1 mylo (nl into lylo). The traitor makes it more fair as the town doesn't have to lynch that member of the mafia to win. Traitor also can get carols to fake to give mafia better chances of winning, thus keeping the setup balanced.
