The Disconnecting is a genuine problem in ranked

Whenever i go into ranked, everytime i win they disconnect and i spent 5 minutes doing nothing essentially, even if they won the first game then i beat them in a rematch they Disconnect. Why the devs do something about this?????

Everytime someone disconnects the whole game is cancelled and i get no ranked points i just wasted my time. I just won 3 games and go no progress in ranked at all today

Everytime i load into a ranked game i get anxious, thinking if i win they will dc and i get nothing. I absolutely hate this and i really am considering putting the game away for this reason.
