Zero visibility

When turning them down gives an advantage then yes everybody will do it.

Pick a carbine (M227 or M4A1 are my suggestions) and then play it until you get Thermals 😁

So don’t give the option to tune it down and stay at a disadvantage? You can change lots of things to gain an “advantage”. Color blind modes, etc. Options are nice. 

A lot of people just don't understand what you are talking about and I don't know why! It's a real issue and there is no fix to it. Dice can easily fix this by adding an icon on the enemies' head on a certain distance when you are close to them (as it was in early access and previous BF titles). And for the those who like it the way it is now Dice can add a Hardcore game mode for them

Would that not be an unfair advantage to the people that turn vegetarian and lighting  off this is a war simulator thats part of war is camouflage ambushes and hiding. You just want to know were every enemy is? I agree that sometimes I have a hard time seeing some people, but iv never just laid down in the open and not been seen.
