Come On Rito

So I've played 54 games of Flex q so far, had a particularly bad showing in placements and thus got placed bronze 4. I worked through this and was in promos to get to bronze 1 and then out of bronze again. Now riot decides to "fix" the matchmaking system, and then places me in Bronze 4 again after my 1 match. This is despite having a 55% winrate from where I started. What the hell rito? Tldr: I played one game and dropped two divisions.
