the target game is a prime example of what i'm saying, because in it i explicitly made it so that mafia was nerfed, it was the whole point of the game, that night was good for townies.
voting night can be good for the game if it avoids stagnation and keeps townies active in the game. i.e. if the whole town agrees nothing will come of day, which often happens, often people stop paying attention.
i do agree with you that in a perfect world, night is generally bad for townies. but in the real world, people can be naieve, random, lazy, bored, misled, etc. and sometimes you just gotta play the team you're dealt. which is why you shouldn't automatically target people who vote night.
