Bgblitz Point System need changes

I have 60% Win and getting 45-60 mmr per win. Lose 60-80 each lose because i get into lwoer mmr teams because there are not enough player que at the same team.
The result? They throw me into lower mmr games. I dont get any mmr because “the enemy team was to easy for me” while i also lose a ton of mmr because “the enemy team as low, i should win this”.

There where not many high rated player but now after legion remix launch it get even worse. there is no reason to que. I won´t win 70% of my games
