This matchmaking system makes me want to pull my hair out.

My last 5 out of 6 games I win lane, but every other position on my team FEEDS THEIR ASS OFF. I roam and get kills in for them, but it makes no difference, they end up dying again on their next return to lane...i beg them to group since they clearly cannot handle their lane, but they stay in their lanes and farm...it's just a vicious cycle of terrible players. I'm by no means trying to say im the best player in the world, but this is the most frustrating thing i've ever experienced. this is the first season ive had this many feeders on my team in a row. I just passed my series to get a 6 game lose streak to knock me back down again....all i need is just one other lane to just go even...or even be slightly behind, but i just cant handle all the other lanes being so fed that it's just a steamroll.
