Not really mate, in fact that “universe” only exists in your head.
Sorry to bust your bubble but there is literally a game developer proving you wrong:
“The matchmaker was designed to try and create games with equivalent-sized groups, especially for solo players, and these statistics show that it’s doing a pretty decent job. We believe that games with equivalent groups create the fairest possible experience, and fair games create the best chance of players having a fun experience.”
Again, it is what it is.
You cant “exploit” the system mate, not beyond the thresholds they allow you.
Thats why in GM you cant 3 stack, theres a specific SR gap per rank you are allowed to have, etc.
Again, this that I am saying are facts, about how the MMR works. Read the link and you will know more.
