It'd be so long before everyone quits because of your stupid match making system.
I normally only have time every night to play two games maxed. Tonight happens to be one of those nights where you get TWO STRAIGHT games where in both games we got two level-20 player in our team where otherwise would have been full 10 level-30 games. I soloed queue both games, and not to my knowledge our team had any groups (the other team actually had group queue by looking at their team names). I don't think I need to go in dept how unfair this turns out to be.
Seriously fix your MM system before everyone loses faith...
