No one is saying it is impossible. I have seen players like Hector and Busta move. They will flank in stealth mode like a motha f**ka. But it's studying moves like that, that will save your a$$ in the field. Always watch your back in cover and always move forward as if the enemy is around the corner.
For me a knife is dead weight. Thinking light and practical.
I'll give $30 to the first guy that has a knife kill on me. But if I turn and shoot you before you can touch me, you must surrender your knife, pistol or AEG (what ever you have in your hand when I shoot you) to me forever. When I say knife kill, I mean reach out and touch me on my shoulder or something. If you decide to not have a weapon in your hand, then it is not a knife kill. Then I get a choice of weapon I want that you posses. Plus I get to shoot you for being stupid. And if you think you can get me in a choke hold cause you don't want to use a weapon, you better put up a good fight I don't go down easy.
Good luck fellas!! Lets see the silly knives. I'll be sure to bring my camera so I can take a picture of the sorry sour puss that tries to sneak up on me.
I love testosterone!!
