"I lose because of players like you"

Yup, i'm sure that you just happen to get horrible teammates every single game for SIX YEARS straight to the point where you havn't improved at all as a player.
Quit blaming teammates when you're the issue. If you started playing the game when you were 13 and you're 19 now and still havn't moved an inch in ranked, then I think you might want to rethink your strategy on blaming your teammates.
