People who are trying to do this are killing pantheon.
Last night I played against 2 friends who were doing this 2 games in a row. My next 4 games in a row one of them kept popping up in my connect screen and then quitting because they're friend wasnt in there.
When a player leaves in connect screen the game automatically replaces them with AI and starts the game.
It may be fun to smash people with your friends, but you are causing broken games for everyone else in the process.
If you want to play as a team play custom mode!
