Spies are a bit underpowered versus cult, and are easily converted. - no-one heals a spy over a investigator, and once the mafia knows there is a spy, They'll be quite and vague, I suggest, if the spy is converted, He shouldn't become a cult, but rather, hear the cult instead of the mafia. - I suppose this brings more hastiness when converting higher roles.
It makes sense, in my opinion. This could be used for investigator/sheriff, but makes less sense.
At the moment, if undetected, Cult ROFLSTOMP the town- Especially in a shitty setup such as; cult, rand neutral, sk & mafia, because people prioritise.
I'm throwing this suggestion out there and don't intend to insult you if you don't agree.
But PLEASE don't say "no."- Constructive criticism is the best kind of criticism.
TLR: Read the post, and don't be lazy. It'll take you a minute, for goodness sake; You spend longer on mafia anyway.
