I honestly don't even know. My last like 9 ranked games, every lane (mine included, about half of them; other half I'm jungle) loses. Teammates ignore pings, rage instantly, and just lose every lane every time. I myself at best go even; I don't take too many risks so my rewards are rarely going to carry that.
If you're losing practically all of your lanes/games you probably don't belong in your rank. You could keep losing and eventually fall to the rank you do belong in and slowly climb out of there. Or you could just play normal games until you get better. Hell, maybe even play bot games to practice your cs so you lose lane less often (or at least have an impact when you do lose lane because you farmed up items regardless).
Also people have bad days, so maybe you just played ranked on a day where you were performing poorly in general. If you lose 2 or 3 games in a row you should probably take a break - play normals or just take a break from league altogether
Edit: I forgot to mention, when you do play bot games, make sure you focus on getting perfect cs and not on getting kills (anyone can kill bots...)
Well, if you are on a losing streak in ranked, I'd probably stop playing ranked.
Like, after 3 games I'd probably call it quits for a little while.
Passed that, stop blaming your teammates, find what you did wrong. you went even? Was that 1-1 or 13-13? If it was that latter, you aren't helping the problem, and are actually causing more of a problem if you gave up the additional gold for killing sprees.
And as always, ward more, ward better.
Kill you're laner 2 or 3 times, get some kills off of roaming, and boom. You're hopelessly fed and you're teammates aren't as under fed.
If you hate these guys, you can always try 
. He's great against most melee tops and his ult allows him to save most teammates from their own stupidity.
Also kind of work for this, but I'm not sure about most of these guys' effectiveness in other things though.
lose enough the game will eventually give you some mercy
You're literally just setting this thread up as a situation where you come out as the loser no matter what anyone says.
Go ahead and whine - you're going to come out of it with nothing useful.
Maybe after you throw a fit more fits and make a few more threads, you'll start to focus on actually fixing your mistakes. Then you'll get somewhere.
