Thank you!
Yeah, that scapegoat loop is certainly possible. The main out would be if the Blaaaming Flock decides they need to start policing someone else and so shifts blame to a different faction. The Flock should be a slow scoring faction, so they need to keep everyone down in order to win, not just get easy points from someone being continuously wiped. In the end, being the Scapegoat is very punishing and will need a good amount of playtesting so it feels right and is balanced.
