Night/Thermal scope and flashlight speculation

[ShadoViper]

So, with the announcement of these scope/attachements existing In the game I have been wondering about how everyone thinks they should work or concerns they have about them.

Here are some of my questions/concerns;

Flashlights: Will they have a blinding effect similar to bf3? (should they?) can you toggle it on or off?(should it be toggled off by default when you spawn?) Will they be necessary for night time. Will facilties have sections that go pitch black if the generator goes offline? (assuming they still have gens)

Thermal: What are the cons for using this scope? (bf3 had one and it was abused horribly) What should be the best time to use a scope like this? (Close range to spot cloakers? For Sniping?) note: They have also anounced that they have an implant that blocks your thermal signature. So that I suppose is a con. But what are the others? If any? This could also help prevent smoke spam.

Nightvision: How dark will the night battles really be? Will gunfire or bright flashes eventually cause your nightvision to fail? (should it?)

What do you guys/gals think about the scopes and flashlight? Anyone else excited to use a 12x scope on the jackhammer lol?
