According to destinytracker, my team is at the disadvantage on the lobby balance a whopping 72% of my last 50 comp matches. Second time this has happened this season...have been at rank 15 twice and got whacked by the algorithm twice to where I've dropped 3-4 ranks in a few days. I'm gonna data mine the rest of the season to see if I can crack the code on their uber secretive matchmaking system. So far the only factor I see with significance is consecutive games with a high KD. It looks like win or lose, if you raffle at least 3 straight games with a high KD, your lobby KD jumps and then it gets nutty.
