Yeah WarRobots did something like that, if they repeatedly cancelled out of a drop-in map because they didn’t like what was chosen or that their opponent roster were not easy pickings, then they’d block those users from spawning into games and just match them with each other.

At some level though you are just against some crazy paid to upgrade person that had no strategy other than a weopon that obliterates you with on shot, and it became unplayable
