i have never seen such a bad queue system

so in the last few weeks i have been working hard to get to gold, I have climbed from s5 to s2. However, after I reached s2 all my teammates are so under skilled that I lost almost 10 games in a role. I tried my very best as you can check my kda and things but my team is not doing the job. I hope riot don't respond with things like oh check how our queue system works because my mmr was at s2 very normaly and things were fine. Then I got placed with people with same mmr but not the same skill either way worse and one game of really high skilled enermy killing off all my team. I hope riot do something because many players play the game to compete and get a rank not for fun
