Relegation Matches

So I was very excited to duo with a friend for the majority of my relegation, we went 5-1 together; but soon the typical matching system problems began. As soon as we start doing good the next 4 matches end up being with the worst possible teammates you can imagine. Now I'm once again ranked at the bottom of the bottom after doing so well in matches with 20+ kills only to have teammates feed. Now instead of enjoying competitive ranked games, I'll spend months just trying to dig out of bronze 4 since that's how this system has been designed.
