The reason this is unbalanced is because stalker has failed to cc doc, and the other MafiaPR hasn't cced cutlers d2. At the same time Rivals are not pressing to joint with a side in order to kill the other rival. They are not negotiating. MafiaPR/Cutlers is not trying to get the Rival to vote with them. MafiaPR is also NOT trying to say who they knifed, in order to wifom who has the knife. In the end Mafia HAS TO bring their best claim game if they want to win. If I were a rival, it seems like town is more apt to screw them, and it is better to try to joint with mafia. Game ends when mafia are dead and that kills a win for Rivals, so Rivals need to keep mafia alive.
If I were to remake I would remake with a Quack, seeing how Apprentice is completely pointless. But quack needs to be able to save Rivals and not partner perhaps.
This is all about Rival politics and timing. It is about Rival getting mafia or whoever is knifed d1 not knifing them. If I were to change this setup I would just take apprentice out of it.
