So we played 3 games, first game we won and got +11 points and then we lost 2 times in row against the same team and we lost -14 and -13. Intresting system. Or maybe mmr doesnt matter but the arena team rating? We were 1.9 and they were 1.4 rating. Hmm..

You get rating based on your TR vs the oppositions MMR.
