Just got de ranked from shotguns to knife because the host ended a game at round 4.I had no downs and so my kd actually went up a tiny amount from the few kills I had. I had to play a round 45 solo to get them back. My kd was over 245 when I get the de ranked and so I believe that rounds has a huge influence in your emblem. This is proven by the noobs that got shotguns through round skipping without even killing anything
