Support/Jungle LF Diamond 4+ duo

This is a stretch, but worth a shot. I'm 27 LP away from my Diamond promos but averaging 22 LP per win. The only way I can hit my promos in 1 game is by duoing with someone higher ranked :(

I've won my last 10 ranked games, here's my OPGG: http://na.op.gg/summoner/userName=x+kp

Thanks for reading.
