I think you can turn of your squads names on the HUD in the sttings if i remember correctly.
But I do agree with on almost all the points. I personally like to modify my guns to try different things. But I would also be happy with a kind of randomized weapon build for every game (Maybe like 2 builds per gun)?
And taking into account that battlefield 6 conquest maps are small compared to earlier battlefield games i would like a conquest mode without the overwhelming amounts of tanks... so a mode with 1 tank per team with the respawn timer on it way up. So people will actually have to take care of it.
The bloom/spread of the weapons will make players slow their gameplay after some time when they realize what happens to the accuracy of their guns withing certain stances, movements and prolonged fire. BUT the ''hardcore'' mode itself would also slow down the majority of the playerbase. Except like a squad of streamers running medics.
