I am 100% positive that abybody who has more than 1 k\d...

...is either cheater or a nolifer that plays 10 hours a day everyday. 

There is no way normal people can get more than 1 k\d because of the time needed for reaction. All those fancy youtube videos where player gets like 20 kills before anybody even notices him are either fake\staged or just a blatant showcase of hacks.
