Mafia: general discussions.

They can either strengthen a strong player or weaken a weak one.

That's why they should be given to players with moderate strength in certain situations. No one complains about random reassignment, even though it's much worse than random chance. As for the rest, for example, I find it disgusting to realize that I've figured out the role of a player with five impenetrable defenses against all actions, but it would be much more reassuring if I knew that he had ninety-five percent defense, even though that's actually even worse. CHANCE, FAITH, HOPE, PERSONAL PREFERENCE.
