You know the risk of random teamgames, all of us get completely trolled by the matchmaker occassionally. (Though I think 85% is a ridiculous exaggeration).
If you dont wanna deal with it then play as arranged team or 1v1.
I can send you my games if you want to see with your own eyes how is the percentage of unbalanced games against me. I keep record of the statistics screen to proove my words. In 85 % of the matches I have more than 200 kills 20 caps while my teammates below 70 and 10 cuz they are 2 or more levels below my opponents. Plus I can post replays every day to show how ridiculous is the matchmaking which I m considering to do. The games I get are 85% unbalanced against me; 10% balanced and 5% unbalanced in my favor.
Playing with pre made team doesnt give you rank cuz Relic is sadistic. I dont like 1v1's in this game. I play 2v2's, 3v3's.
