You have aim assist on every gun that actually tracks people through walls, but the game makes you miss constantly when it comes to knifing a person right in front of your face. I understand that they got rid of the lunging from unreasonable distances, but there should at least be a little consistency when it comes to knifing...especially when you don't have a secondary assigned and you have run out of bullets in your primary.
Should knifing beat guns like it did in other games? No.
Should knifing at least register a kill when you swing at a persons back from .5 feet away? Yes.
I can't count the number of times that I have missed someone 3 different times only to watch them reload in front of me and then shoot me on my 4th attempt. Please tell me I am the only one that thinks this needs to be addressed some point soon.
