I was under the impression that 2 Masons vs 2 Mafia at 9 players is relatively balanced
Add in the two neighbors, that's at least three implied named town roles in a 9 player game.
To help the mafia I provided them with a free night one mason kill. A VT d1 lynch and a VT n1 nightkill, leaving the mafia in a situation where there only CC is one other VT, leaves a sort of awkward scenario.
Of course there's neighbor WIFOM, especially with my name for the setup, but I figured 4 named roles vs. 2 mafia (essentially) goons is a bit townsided.
But if I'm overestimating that then the informed can go away. I just wanted to help the swing of the first two deaths.
