I just matched into a Comp game, had one teammate named "The Rains Down In Africa".
He threw the match constantly by running straight into the enemy Rift as the Spark was moving to our Rift. We lost, obviously, and I lost over 150 points on my rank. I was annoyed, but not super upset. The next match, I have the same teammate "The Rains Down In Africa". It's a Survival match. At the beginning of every round, he would jump off the map until we were out of lives. I lost another 150+ points on that match too. I will not be returning to the competitive playlist if I am going to be punished for teammates that are blatantly trying to make the game worse. I was one match away from completing my Promotion to Platinum.
