I personally feel that Mason Leader is very very weak outside a "Mason themed game".
I would ask that a change be made in regards to masons and how they work in general. I think that mason leader should have the option to recruit town members into the masons as a secondary role. The person in additon to their existing role would be able to join the masons at night in their evening chat.
Mason Leader Goon recruits Investigator Koi
In addition to his normal abilities now Goon and Koi can chat during the night sequence.
I feel this would make masons strong and also allow mason leader to play in a game with civilians off.
If you try to recruit a mafia/neutral it plays the message and fails like normal.
I am not sure if this is able to be implemented but I think it would make the Mason Leader a fun role in a game without civs.
