I hardly ever get matched with good people.

I'm not saying that I'm really good, or that I always go positive, win lane, etc. What i am saying, however, is that while i do good most games i hardly ever get even one person who does good on my team. I could deal with at least one person who does good besides me, but when everyone feeds but me (not always) I can't do anything to help. Nearly all my games are with full team feeding. The other night i finally got close to a hundred points cause i got 2 games in a row with good teams. The only games that i can remember at this point. But today i played three ranked games and i was the only one who did good in any of them; other than a vlad when i went nasus jungle. notice that i didnt really do good that game, but i was nasus, so late game is good, and i think i even ended positive. I then proceeded to go down to 60 something points. The point is it seems as if the entire other team is gold when mine is bronze, and i cant get out of bronze to save my life.
