I don't usually host, but would like to start. At the same time, I want to explore new meta-game possibilities. I'm thinking of disabling last wills and enabling PMs.
Please listen to the reasoning: disabling the last will allows the mafia more options to deal with power roles (most games are still favoring town from setup). To make it so every sheriff and investigator won't have to say everything as soon as they find out, the PMs would allow them to create "living wills" in people they have cleared. This would create many other situations like giving SK's a better chance (they desperately need it most games), indirectly buff to blackmailer, and perhaps make more varied compositions in set up.
