Years and years of riot editing and fixing the ranking system for games like this to still happen on a consistent daily basis:

I just don't get how they're letting this still go on.
I'm starting to understand why people buy accounts, power rank, and other methods of not having to deal with this. 
You have a good game
Everybody else in your team by chance happens to have a bad game
Yup, it's riot's fault
^ average person who complains about matchmaking ^
p.s assist's aren't merely a number. they mean more than you might imagine
edit: with that one assist, it looks like you got quite a few lucky last hits, and used that as a basis to blame your teammates. are you in silver? edit2: yes you are
because people don't have bad games... there are games i have gone 0/8/3 and others i have gone 6/2/15. People have bad games and they have good ones. Looking at a single game says nothing since like i have said, they could be having a bad game. You have those games, I have those games, the pros have those games. It happens to everyone
Don't say anything to them, though...you'll be banned for being mean.
Don't worry bro.. You're not the only one..
People have bad games. It happens. No need to get mad at Riot about it.
"look at me i did well but my teammates didnt"
you cant "fix" someone fucking up
im sure you're never had a negative kd ratio in your life right?
welcome to season 6
the season where the first blood makes u snowball like never before and almost impossible to comeback, so obviously if they snowball ur team will keep feeding because there is no counterplay to that

I will update regularly with screenshots to just sweeten my argument.
Not everyone will feed, Heck sometimes not even most, But there is CLEARLY some sort of difference between skill if I'm going the statistics I am and they go how they do, I won't be counting any games I'm adc, It's my worst role and I tell the queue every queue I'm in.
i dont see how riot can fix this "problem". There's alot of things you can do if you truly believe that you're superior in skill than the average skill level of your teammates. It seems like you play cassiopeia alot, who isn't superior in roaming, so helping your teammates out isn't happening. This is a team game afterall, expecting 3/3 lanes to win is too much. Besides roaming to help your team, warding helps, pinging, etc just overall team effort activities. In this snowball season, a single lane that wins can win the game. How to do this when you're winning lane? help other lanes. even if they're winning, help them. even if the enemy is at their turret, dive or 3 bot to get turret. anything it takes. What should you not do when you're winning lane? do nothing and farm. What will a 10/0 cass with 200 farm at 20 minutes do against 5 averagely strong enemies? nothing. it's a team game which seems to be what you're mostly struggling with. Again, a person cannot be labeled a certain skill level because there just are too many factors. Tilt, bad games, being forced into a bad role, etc. however there HAS to be a method of labeling skill therefore MMR is released. Riot isn't too fond of labeling skill levels of a personthough so theychoose to hide MMR from the public. If you thoroughly feel that this is all BS and that you are just superior than your teammates, then w/e play hypercarries or something like jax/kat/karthus
TLDR: Riot can't fix something that can't be fixed If you're winning lane help other lanes. Stomping your lane and carrying hard is possible but is rare/difficult and will only take you so far play hypercarries if you believe you are just better.
I would cover up those names ASAP if i were you.
i have seen worse ones
Your last 10 games have been 5 wins, 5 loses (50% winrate) according to lolking.net, one of which an 
was carrying your team with a 14/6/17 KDA (you had least damage despite building full AP Nasus). I understand that it seems like you get unlucky and are stuck with people who are performing badly, but you are averaging normal matches with a variety of players who will both do bad and will carry.
We tend to see the more negative sides of things more clearly than the positive, and remember the games that everyone else did badly in rather than the games in which that one player carried us.
