I tested QM. I would like that QM is pulling you automatically into a room, if you enabled QM but like I said I tested it. (Team room was up, no game running, teams set to like and it was not pulling me into this room) And it's much easier to look for the right room instead of clicking on the Check button every minute to check if a room is up.
So I would like to change it to autopull and manually disable it, if you are in the right room. Else QM seems to be useless.
Edit: And even clicking on Check button, while a joinable game is up has no effect at all. So it seems to be broken anyways.
