What is this

Hello. I'd like to start by saying what the fuck is this. I got silver 1 going 5-5, at rank platinum 3. I'd get gold 4's, silvers, challengers, all of that you can think of in these games. How in the world do you expect this to be fair? my p1 friend went 4-6 going against around the same elo of players, duoing all of it. and went p5. Let me know what kind of fuck shit this is. Sorry, pissed off at your system. Also, you do know flex 5v5 will become the new draft mode right? Nobody's going to take it seriously. they're going to take is as serious as draft, more serious than blind, but not as serious as solo/duo.
