Weapons need to deal more damage

I've been testing for some couple of hours and I can't stop feeling the sense that some weapons feel week especially the p18 pistol that is like shooting gummies you need to put 5 to 6 bullets on their chest to put them down, and same goes for the dmr's you need to shoot them 4 to 5 on their chest and 3 on the head to kill an enemy, honestly most players will not land that amount of shots with out missing 5 to more shots to any target especially if they get surprised for an unknown enemy. Some guns fell well but then you can find yourself with the m4a1 that is a **bleep**ing killing machine at short and medium ranges and that's ok for me. Don't get me wrong I don't think that battlefield needs to be a tactic milsim game because it never was and doesn't need to be because it's an arcade fps,  but maybe you could increase the damage output to make some guns more lethal, because I've been using the pistol and the enemies were practically laughing at me. I've played battlefield since BF3 so I'm not a new bf player. 

If you read this post I give you my most sincere thanks.
