You asked for a clip and you got it. Also you're acting like johnqt, Marved, and Derek doesn't have similar mechanics to him. johnqt and Marved have won a LAN and Marved mvped. They're all professional players for a reason.
It's way more crazy when someone gets a 3k like that if they have a Vandal but when someone running mach 10 shooting 20 bullets per second and each headshot is 50 damage it's not that crazy.
