Aha, you can literally do this to get an “easy” Diamond.
If your a high Onyx 3, get 4 top players to smurf account for you.
They play support, you get all the kills.
You will most likely be paired against lower rank teams (4 unranked or low ranked players according to the game in your side will manipulate this).
And there you go, easy Diamond
This is why I am against having alternative accounts.
It literally seems like I am the only one who doesn’t actually have one
But they mess and manipulate the Ranking System.
