Ranked levels Playing with predators

So I was diamond 2 a few days ago. Went down to diamond 4 easily, so pretty annoyed about that. 

But almost every game I load up in top 500 predators are in my games and previous predators also which is fine. 

The top 500 is a issue though as I'm diamond and constantly fighting Masters and top 500 every game. 

Which makes it really difficult to level up. And if you solo and let the game find team mates. They are all seem to be gold's and plats... 

I feel that people should only fight players on the same level as you are at the time. Diamonds should fight diamonds and so on. 

I think people could level up easier that way and it would show their true level.

It's annoying because higher level people will beat you. You lose RP not level up and then lose the rewards. When the master level players can't lose anything at this point.

Something need to be done because is unfair.
