Ive found the strategy to skip this incompetent matchmaking system

You do your placement, get placed way too low ranked

Once your placements are done, feed every single one of your next 10 games. Your MMR will drop drastically but you wont lose too much league point

Maybe up to 15 games just in case

After that you can climb back at your rythm, but will less bullshit matchmade games
