Game #5 Never going to be able to play ranked

First two games i posted, had some person who gets toxic and takes my jungle camps. I won 2 games after that. This game I had a master yi. I didnt help him 5 minutes in after he dived zed and shyvana. I was oom... He raged and refused to gank my lane or give me blue. After fizz gave rengar 5 kills, he afk'd. Throught the entire game, yi dived 3-5 people alone.
