I am in agreeance the knife is a huge issue. One it SHOULD not kill with first strike and two it pisses me off that you can killed killed with a knife from clear across a room! ZIPPER YOU NEED TO FIX THIS!
totally agree with the these comments. Getting knifed from 20 feet away is bad enough but when you watch the guy run through your spray of bullets to finish you with one swipe is getting to be a joke.
you should at least have your targeting cross on the other player and actually make contact to ensure a one hit kill. All other swipes from afar or non-targeted, should inflict minimal damage
