when i use melee weapons, i cant seem to get a hit on zombies, especially the crouched zombies, although standing zombies have this problem as well, but not as badly as the crouched ones. it has made it almost impossible to engage in combat with zombies with out a gun, because they seem to work better, but i haven't been able to test that. It makes it extremely difficult for me as a fresh spawn to get gear, because i have to run or try my luck at maybe hitting the zombie.
