I just want to say, it is kind of annoying when you set up or join a 4v4 match, and then end up when either one of your teammates and/or opponets ready to duel, they just have to confirm, and then you wait but they didn't confirm it. At first I though it's okay, they must be offline or something, and there is a timer that will automatically make them decline the confirmation if they wait too long. But after they leave the duel, they right away join again, and then purposefully refuse to confirm, so I end up waiting for whoever that is refusing to conform the duel to leave.
