How to deal with feeders???

I'm a bit too frustrated with the matchmaking system after a series of games where my kda and general skill has not mattered in the victory or loss of my team. My summoner name is WalrusBees if you want to look me up on LolKing and see what i'm talking about. Anyway, I still think League of Legends is a really cool game, but I was wondering if there's any way I can play alone, or in a format where I contribute more to my team's success/loss. I know there is a 3 v 3 mode but I would like to play in Summoner's Rift. If anyone knows about something like this, or at least a technique to help minimize the damage of a team playing a bad game, please let me know!! Ps If it helps I normally play mid using , , and [slayer-pantheon-thumbs]
