LOL, I'll admit this is me. I don't care how many times you kill me I'm going to keep coming back over and over and over again until you die. Sometimes I'll get killed by the same guy multiple times like 2+ but it doesn't happen that often especially if their sniping. I'll just bust out the knifing setup with the care package glitch, if you can shoot me before stab you in the face more power to ya.
I'm not that great at this game depending on the map I'll get a pretty good score though. Maps like Afghan, Terminal, Favela, Skid Row and Sub Base it's pretty easy to get top 3 if not top score doing nothing but knifing. It's not uncommon for me to lead in kills and deaths for a map, my k/d ratio sucks but I don't care I never stop running I spring 100% of the time.
