I don't mind Cults so long as they're limited. Let the Cult Leader recruit 1-3 players max, and only make it an X-Shot ability. I'd rather not give them a kill ability, but let them bring Cops/Docs/anything else into the fold. Cults are dangerous, especially when they have 4+ members in a Large game, and growing. Make it so that all the Cultists die if the Leader gets taken out, or have the followers revert back to what they were.
