Weapon and kill Balance

Look I have no real complaints so far with B06 it’s fun I Like The Zombies.. not a campaign guy so wont play it, But some of these shoot out battles I’m having in multiplayer make no sense.. and its not an skill issue I feel I’ve adapted quite well to the omni movement but it’s like I’m putting my whole clip in some of these dudes and they Kill me with the nastiest sense of ease that it bothers me.. Need Weapon and kill balance upgraded because this is insane
