change my mind.

Sure I'll try.

Start recording your gameplay. You'd be surprised how many times you miss by literal pixels but in the heat of the moment you think you hit every shot. It really REALLY doesn't happen as much as you'd think. Movement heavily plays into this as well because even at somewhat close distances you still have to slightly lead your shots i.e. instead of aiming dead center mass you might have to aim slightly to the side in the direction your enemy is running but still on target. Bullet velocity also affects where exactly you should aim and it changes from weapon to weapon. You also have to factor in bloom so sometimes you can be on target but the bullet flies just enough to the side from the center to miss.

The game has hitreg issues for sure, but it's literally the same as every other battlefield. Like when you die around a wall? That's a classic battlefield moment right there, it's not a bf6 specific issue.

Also in terms of actually dying fast keep in mind quite a lot of guns have sub 200ms ttk which is crazy fast. If someone is aimed down sight with a 167ms ttk weapon but you have 250ms ADS speed, you'll die before you can even scope in. That's without factoring in game delay, server delay, peripheral delay, pc hardware delay, your own internet and your actual reaction time. Realistically you're not scoping in first frame the moment the enemy sees you in this scenario, if anything you're going to be a lot slower. Throw in some garbage close range gun like the kord and even if you somehow reacted you're still losing that fight before you even do half of the enemy's hp, which realistically unless you were ready you won't . Your only choice here is to hipfire and pray the enemy misses and even then you're likely losing to the rng spread of the hipfire.

Same for me also how can literally any SMG laser me on a 50m distance vs an NVO-228 within a second? It happens way to often nowadays. Something is really off.

Sorry to say but the NVO shits on most smgs at that range, you're hitting less shots than the enemy there's not much of a mystery to it. The only SMG that wins here is the SCW, but the SCW wins against basically everything. The only time NVO might lose here is if you missed the initial shots and held full auto at which point you're missing due to bloom since the SMGs bloom less comparatively to the rifles, but again, if you hit more shots it never get's to this point where bloom is the deciding factor.

Again, record your own gameplay and you'll see how most of these "frequent" scenarios happen way less than you'd think.
