Quick play is the worst feature the devs added. It just dont work. There are lots of things wrong. As result almost no one player Quick play, so waiting times increase. And as result of the increased waiting times, even more people quit playing Quick play. I already expected this when they announce the feature.
When the features was released, i already made a thread about this issue:
I would advice you to join the ranked queue. After some placer matcher, you will most likely face only about equally opponents.
