I like the element of randomness. I hate knowing that every time I lose it isn't because they were better than me, it's because I didn't try hard enough. I play games to have fun, not to push myself to the limit every time. What precipitated my mostly giving up multiplayer was when I noticed I was forming my habits around winning and it was working. If my room lighting was good, if I drank coffee before a match, if I played during the right hours of the day, I won. When I started avoiding using the bathroom because having to pee made me more alert, I knew it wasn't worth it anymore. I like games, not sports.
Well if you chill a bit in the system your rank will naturally go down and you will get worse opponents. Many people do that.
Its much better system than one out of 5 games being balanced. Not sure where the problem is… maybe you dont like about yourself that you are actually competitive? I mean i played esports on pretty high level and i am pretty sure not going to a bathroom to keep you alert is not a thing. Sounds like pretty serious urge to win.
Good thing is i think one can learn to be less competitive, enjoy it more and it makes people even better. You can work with this and not make it all out competition.
