I've read many of your posts on mm and you are not wrong.
"Everyone should play their exact equal and everyone should win at the same rates overall.." - I'm not for this idea either, but rather facing people more or less in the same ballpark skill wise. And I'm only saying that as a compromise because we know sbmm isn't going anywhere. As it is now it's far too aggressive for some people, like you, who can only achieve a 2% win rate even though you are a better player than most.
If a player wins 5% of matches, he's losing 95% of them. To me that's a very small reward vs investment. And that number is basically being forced on us, not earned, so why even play?
Ever wonder why other masters players have higher win rates but not you? That's the real question. I saw a pred today with a kd of 16. Yes 16.00. How is he pulling this off if he should in theory only be playing other preds / masters? Favoritism?
Don't get me wrong, I think sbmm should die in pubs. If only the top 10% of players pose a threat it makes sense that they would win more and deservingly so. But it also means I would be seeing them much less in theory. The rest is a dice roll. And I'll be ok with that. But right now better players are being forced onto average players most of the time due to the whole playerbase not being accessible to each other.
