Stop giving me unwinnable games, I'm done with this lose streak

All of your games except your Jinx and Ziggs games were close in terms of gold until the end, often with your team being up in objectives since your last victory. You seem to have issues securing wins when you are ahead and pulling ahead in even situations.

Of course, that is just what I can gather from your match history.

matchmaker is broken. it uses MMR instead of ranks to match people. And it doesn't make sure everybody has the same MMR. it just makes sure that both teams have the same total MMR. Which leads to lopsided games when 1 team has a midlaner with high MMR and the other has a support with high MMR.
