What Battlefield 6 done wrong (solid video reference for comparison)

#Sound: 
IMO Guns in BF3 sounds like a small nail gun ... at that time coming from BFBC2 to BF3 the guns sounds were my biggest disappointment.
And as far as I remember no BF after BFBC2 made loud guns , BF4 sound system was better than BF3.
In general sounds in BF are very tamed and not loud like for example : Squad.

I agree In BF6, the kill hit marker sound and visual effect feel very cheap but there is an option to turn off the kill sound effect.
I also agree on Test range being for guns only.
