Riot Matchmaking to good

I had to sit on 2200 g because I spent the last 5 minutes defending the nexus turrets from all comers until my fateful last stand at half hp against j4 and my game long rival yorick as well as near a dozen super minions. I did for j4 but yorick and the supers finished me off... and then we lost because my team sucked even by bronze standards but hey next game I'm going to get a silver 2 quality team... right there's karma in matchmaking isn't there.
