What the hell is up with MM?

Matchmaking is laggy as hell, takes quite a while (although i can understand that due to it being Ultimate Edition time right now) and the people are absolutely the worst. People either leave 2 seconds in, or they just sit there for the whole game. I have played about 6 games so far, and I have not had a normal one yet. Why the hell do you people do this -Yoink-? One game… Please…

UPDATE: Finally got my first normal game, but ah, it can never be perfect can it, my game just had to crash
