They may come back if they have a real purpose in the game
MMS was kinda the knocked down version of night vision already, lets you see through smoke and walls.
Even better make an entire map that is near black and night vision is equipped for all. Make it more like real night vision though with one eye view and a narrow field of view. You would still have your non-optic eye if you run into a bright area or flashbang.
I'd be all for dynamic maps with varying weather and time of day, but I don't want to be playing entire matches with NVGs on and seeing nothing but green.
If people really want NVGs back then maybe have a darkened area on a map, underground tunnel or bunker system or something where you can use them. Personally, I don't see the appeal though.
