A fair game - specially a nightless one gives scums a boost cause People are not robots.
but if you want math
removing one citizen (assuming everything is random and this won't be use as a tell for scum hunting - which is a faulty assumption from the core) the game is 6 v 3. Goons need to get 3 town lynched. town needs to get two scums down.
The chance of town win is = 1/12 + 2(1/14) + 3(5/84) = 0/08 + 0.14 + 0/17 = 0.39
so if thats your way for measuring balance your game is so scum sided.
