Matchmaking system

Does anyone else find it crazy that it is possible to end up having a team that will run in circles and die upwards of twenty times in a game against people that are on massive winning streaks and just completely dominating ranked. Like, that happens to me so often. Not to mention that over 30% of my games have AFKers (Not even joking.) I have kept track over the last few days and I have had 16 afkers, to the enemy team's two (Also, this is not connecting type of afk. People always assume that I rage at them, but that isn't the case. I just ask them to try not to die and play safe, also ward.) It seems like it is next to impossible to get matched with people in your current skillset. My recent games are pretty awful, but it is usually because I'm working against carries with 15+ kills. It sucks! Does anyone else have this problem? I'm not raging or anything, I am just hoping to get some slightly closer matchups. It cannot be that impossible to put a little more effort into calculating MMR, and who knows... Maybe that would make the AMAZING games actually happen more than once every couple months.
