Placements and ranked solo/duo.

I'm seriously pissed off at how much other players factor into ranking. I lost 6 of my placements because of hardcore scrubs, trolls and afkers. I went at least 10/4 every game but I still manage to be placed at bronze 1 what the f*** is this sh*t. Not only that but they've also dragged me down to bronze 3. Fix your god damn queue.
