In a game that relies so heavily on team comp and cooperation it seems pretty silly to have a drop in/drop out function. Should make it always start a new game. Never just drop someone into a half finished map with someone they didn’t pick. Also to stop the blatant “if I don’t get my way I’m out” prevent people from dropping out only waiting one minute the potentially doing the same thing, make it so they can’t start a new one until the old one is finished. But give them the ability to reconnect.
