Just some friendly advice

If I'd have to give some friendly advice as well, it's that this game isn't meant to be realistic. Battlefield was never realistic. So if they were to change it according to the things you've mentioned, it wouldn't be Battlefield at all.  It'd be more similar to Squad or ARMA. So why exactly are you asking for this?

I disagree completely.  Battlefield used to be the more realistic game and CoD was like an arcade game.  Did you ever play any of the early BF titles.  Other than environmental destruction they were very realistic.  I’m asking for a little more realism because if I wanted to play CoD I’d just play CoD.  

There is so much wrong with BF ballistics-wise it’s not even funny. From recoil to kinetic energy it’s absolutely stupid, and my biggest gripe since DICE took over is the favoritism for over-accurate small round guns like SMG.  BF3/BFBC and prior had actual balance in kits and accuracy. Since then it’s almost wannabe CoD where players use nothing but rapid-fire guns. 

That said, it’s a game. We’re not gonna get realism when it comes to bullets, recoil, and damage. What we do need is balance. Small guns effective below 10-15 meters with fast falloff of accuracy. Single fire accuracy after that. LMG accurate lethality if on bipod or hipfire at close range. Not a map full of SMGs bunny hopping around corners or picking you off from rooftops. 

BF1 is what you're looking for - much more satisfying gunplay and sniper fire.  BF6 turned out to be the arcadey light and "fun" (degenerate Disney baby version) silly Battlefield.  It's so ridiculous, it's designed by the former COD staff.   They're not taking Squads nor Tactics seriously.  You may as well call it Apex 6 or XDefiant.  It's not Battlefield, men (I've played all of them).

God, just look at the scoreboard:  "K"...."D"...and "A"......where tf is the rest?  NOT Battlefield. 

Yes, I've played all Battlefield games.

You know why Call of Duty was seen as the more arcade game? It's not because Battlefield had absurdly realistic gun handling physics or damage calculation based on the caliber of gun. It's because Call of Duty had smaller maps, faster gameplay and most importantly it had health regeneration. Something that was quite controversial at the time.

These comparisons to Call of Duty as usual lack any substance. If you actually start comparing them properly, you'll see that while there are certainly similarities, there are also many substantial differences. If older Battlefield games were realistic, then try to explain why the Project Reality mod was developed for Battlefield 2. It wouldn't even have a reason to exist if Battlefield 2 was all that realistic. If you wanted realism at the time, you'd be looking for games like Operation Flashpoint.

I think we need to recognize that the legacy of the Battlefield franchise doesn't just include Battlefield 1942 and 2. It includes all of the Battlefield titles that followed afterwards as well. Battlefield 6 shares the most similarities to Battlefield 3 and 4 and is honestly a pretty good successor to it.

No game is completely realistic but they had much better balance.  Caliber and range of shot mattered.  Moving affected you ability to keep crosshairs on target, no jumping and shooting, bullets dropped and distance shots were difficult.  I compare it to CoD in the way of smaller maps and rate of fire with low recoil is king.
