Riot wtf is happening with your matchmaking? I'm not some Olympic-class weight lifter what is this?

Past 3 Ranked games in a row I get stuck with people I need to fucking go balls to the walls hard to carry and it's knocking me on my ass how clueless these people are both in game and when they all gang up and bash the only thing that kept them from losing.

I'm sick of being dragged down into the mud by the bottom of the barrel trash-heaps with keyboards and then having to see their incompetence spewed onto a screen when they go after me for calling out their stupid picks.
