Always thought it was a cool idea that you could bump into a pro in a deathmatch game, and it happened to me a few days ago. I immediately noticed that the Phoenix in the lobby was either insanely good or cheating.

After the game I realised it was Shao from FPX, warming up right before the game against G2 (so probably hyper focused). I did not even manage to get past 24 kills, when he had 40, which I honestly have never experienced.

Edit: Shao was so insane, that I totally overlooked another pro: the Reyna is Bonkar from Team Finest.
