… yeah, why the fuck isn’t matchmaking rooted in which character you want to play as / with / against? You shouldn’t be slapfighting randos for who gets to be the newest gimmick. You should be looking to pair your main guy with your favorite other dude, and running across the same other-dude mains week-to-week.
Even just presenting people with two or three lobbies to choose from, instead of dictating “You will play HERE,” should massively reduce how much people blame others.
