Missions should be capped to a maximum of 4v4, because the game is balanced around 4v4.
4v4 is an objective format
Any popular game has an objective format in which the game is played
counterstrike - 5v5, league of legends - 5v5, wow arena - 3v3, pubg - 4v4
This game has turned into a chaos clown fiesta fight club every mission, and its not good
You have no agency over how the game is played, or what the format will end up being. Its pure random dogshit
Its actually insane that I even have to bring up this point which is complete common sense, enjoy your dead game
