How to play Battlefield 4 in infantry mode? Netcode issues

I briefly searched this reddit for look of similar topic because the case is quite popular ( i think?).

First of all, the reason I am writing this post are the huge netcode issues that I am experiencing. As the game and ping are smooth I am constantly a victim of situation where my client ‘recieves’ a hit, before I can visually see the enemy player. It feels like other players are one shotting me from their weapons. I am aware of rollbacks (escaping to some cover and being there for quite some time, then getting killed through it, my record is a death after ~1s). Enemy players are usually running with AEK971/Bulldog/AWS/MG4/PKP/ACE23, where I understand the imba of those, altough I cannot win in head2head encounter because I got ‘one shotted’ or hit already before I can see them, even if I carry one of abovementioned weapons.

These “I can see thing” situation is present when I am moving around the corner and the enemy is in the corridor as well as when the enemy is moving through his corner and I am aiming in the corridor. In both situations even if I am aim walking (ie. holding MB2+W) only walking or sprinting I am likely to get shot, whereas my enemies are shooting me down well from any of their stance positions (run/walk/aim).

I am a fps veteran (started from cs 1.3), therefore please do not try to assign me to ‘noob types’ - “maybe you don’t know how to play durrrr”. For isntance, in bf3 I can get pull a 40/10 with a wpn other than M16A3 on other map than metro, therefore this is not the case.

My frustration in bf4 is following: I can get lately 1/2 k/d ratio only because I shoot the lower (ie >100) players in their backs, and this is not satisfying gameplay.

This netcode random factor is completely against me. Where I could understand the case if I would also pull out few random kills on random bullet spread, but somehow it’s just isn’t working for me.

My questions to good bf4 players is:
What is your success recipe for netcode issues on infantry/ Locker map types?
How do you pull out such sick 1shot kills on head2head encounters?

Preaching to the choir

Since relevant patch, Low ping servers allow me to play with none of this frustration. Not sure about your connection , but I only play on servers with less than 20 ping. Good luck
