When you get back you will find your character has been in a loop playing vs AI. Go watch a movie, do the dishes, play some guitar, you name it. You can literally walk away at this point.
This makes it so you don't go afk during the match. Join 2v2ai with a friend, pick your characters, and lay your controller on the table, so that the thumbsticks are pressing in any direction. Instead of raging over it, why not get the gear yourself? This is probably game breaking, but it looks like thats happening already with everybodies rage over everyones 108 gear.
