Matchmaking in FlexQ is a joke
Yes yes yes, the obligatory trolls saying 'git gud' 'ur bad' etc., 'You're just bad', etc.
When you're climbing for Gold V in flex for the bonus skin, only to find matches like this extremely common, especially in promos, it's a little ridiculous
And I know I will absolutely be inundated with mindless chatter about how these players are not yet ranked in flex, so therefore they are in my games. It seems to happen very often that the team with the higher MMR wins, as typically they do so by a hundred or more points (like a Silver player in lane vs a Plat player; almost always results in the Plat player winning and snowballing before anyone can even do something to help said Silver).
But yes, totally reasonable that to reach S1 in Flex you have to near constantly beat Plat players or Diamond players.
I mean seriously, if I wanted to play against Diamond or Plat players I'd just do normals. I don't know if Riot knows what matchmaking is, probably not based on the number of Diamonds I get in my normals, but stuff like this will cause a lot of players to ultimately get upset and quit. When the game is telling you that "You're bad" b/c you are in the 'Silver' bracket of FlexQ (constantly facing Plat+ mains of their roles and champs), and you're struggling to climb b/c of it, it's a little silly.
I didn't want to win my promos anyways, which is why I was glad when I got repeatedly matched with a (Plat 2, yeah to get S1 you just gotta beat a Plat player, have fun!) Lee Sin OTP for both my promo matches who has more games on Lee Sin than I do in LoL.
I don't even want to imagine what you have to do to get to Plat in flex, face off against Challenger players?
Again, before I'm inundated with repeated spam about 'Every Q has a different MMR', stop to think about that for a second, shouldn't it make sense that the game would use your pre-existing rating as a baseline for new Q's? I'd hazard a guess that a Challenger in SoloQ isn't going to struggle all that much against Bronze-Diamond players, so it wouldn't make sense to start their MMR low. You shouldn't be Plat and facing Silvers or Bronzes in Flex, it's almost unilaterally going to end with the team who simply has the higher amassed ranks winning, as typically rank denotes consistent skill.
There needs to be a better system in place, the one we have doesn't make sense. "If you want to pass Algebra 1, you better know Calculus and Trigonometry!", it makes just about as much sense as that.
Just my thoughts, I think we need to see some serious changes in the upcoming season.
