Ranking system is trash not everyone has no life and plays on a mouse and keyboa

Sure, your only option then I guess is to try different times of day to see how the lobby looks at different times. 

I noticed when I just got through Platinum rank that it varied greatly depending on time of day. 
I would get into some games with Gold players, and more games with Preds and Diamonds while in Platinum 😂

And then certain time of day I would get consistently Platinum players. 
Just because there were more people on.
