I have people go afk in these games every 3rd team game because they just give up when the opposite team is too far ahead in score.
Its not fun with bad team mates, makes you wanna give up and go afk.
Seen it often enough that people do this + people complain about these game modes the most (that they want a separate queue for example for team games) so making a compromise to just lower general game length potential (it can still last full 5 minutes) would be nice.
