I hear you Sparky, this mode can be very enjoyable when both teams are equally matched, but unfortunately oftentimes the matchups have a big gap between the skill levels in both teams.
I think the one that was paused all game could be related to some kind of new issue that’s happening.
I can only imagine that the ones that keep the ball to themselves and don’t pass it, score own goals, and this type of unacceptable behaviour are possibly young kids.
Players that quit I imagine they can see how the game is going to go and don’t want to waste their time. Could be connection issues as well I suppose.
