I understand why HDR is in the game. However, when you're using NVGs, the brightness and contrast of the image shouldn't be adjusting itself. It should stay completely static, with the exception of having a means to change the sensitivity of the NVGs as has been possible in previous releases. This would help to greatly increase the realism of the NVGs, and make them more naturally balanced. Instead of getting screwed by a light source making it so you cannot see in a darker area when you normally would if HDR was off, you'd be screwed if you tried to look in that illuminated area at the same sensitivity you needed to see in the dark area. It gives the player the control over their NVGs so they aren't needlessly blinded or unable to see.
Lights should blind people using NVGs (except potentially friendly vehicles, as there are ways to filter headlights now so they do NOT blind friendly units, which helps A) not blind infantry and B) infantry identifying vehicles in the field), and you shouldn't be using them if in a well illuminated area.
