It happens, there are times when i die by three bullets when i am putting a clip in a guy, and then there are times where i am getting a clip put in me and i turn around and kill him with a couple shots. So ask your self this have i ever killed anybody when i knew i was doomed and just sprayed bullets for last resort? i am going to bet the answere is yes.
Is it a connection problem.... probly (and i am not saying on the users end either...... "I got 200 download stream blah blah blah"). Will it be fixed----- i think it will get cleaned up but you are never going to get perfect hit detection in a p2p format.
