There should be some kind of spreadsheet or something that explains each and every outcome of a match explaining who will win in X scenario at the end of the game etc.
Example: “If a Prince and a Assassin are in a 1v1 on the last Day, Game will end with Blue Dragon winning”
I have lost one too many games as NK/Evil roles because of my lack of understanding the “weight” each role/class has when if i killed the Prince or something that night, I could have won. I’m sure many other players agree with me on this point.
