Is it playable? - Yes it is.

Are there the right ammout of mafia and villagers? Yeah, seems like it.

Is it ballanced? - NO

This setup is horribly unbalanced , and since the site mentality ruins the games even more (Most ppls just bw around) it makes the setup even more Unbalanced.

After 200 games i bet the mafia wll have at least 80% win rate.

Serious, why comp this setup if it is so unbalanced?

I request the setup to be removed immediately.
