It's not that easy.....WE NEED A SOLO OR DUO MODE.
I always have teammates quit because they don't like my jumping spot or because I chose their character.
Adding a solo or duo means you won't be fighting a full squad to get a win.
Those that keep campaigning against it, if you don't want solo mode, you don't have to play it. It does not affect your game what so ever, in fact it's more likely to improve your experience as you will be more likely to have players in your game that want to work as a team.
