Mafia: general discussions.

comments about imbalances or flaws in the balance after a game are no different from Dag's tactics and punishments.

Do I need to repeat myself?
Okay, I'll repeat. When you take on the role, the balance suddenly shifts from very good and balanced to being skewed in favor of the opposing team. And further suggestions for working on the "flaws" consist of weakening the opposing team and strengthening your own.
Simply because the concept of correct balance shifts. It's psychology. There's nothing you can do about it.
