I think that if GRW and GRB featured that Watchdogs Legion mechanic it would have been great. GRW has not GRB amount of settings, not that it needs them, and I think this proliferation of settings is just an excuse for more mostly unnecessary accessibility to the game. But, going straight to the point.

I cannot test this in the game, I just thought that enabling the "Slim Shadow" perk coupling it with selection in the settings of low enemy - spotting- awareness, one could actually, manage to get less spotted, and this of course together with some player appearance, role playing (which I know the game doesn't care of), so dressing with a Skell clothes or maybe just PMC\Sentinel look or whatever it is needed for a specific case, could lead to have a "Social Stealth" experience, aka, you go in a place and still try hard not to get spotted but still will be able to walk somehow "almost" taking normal routes, that are not crowded, to get a sort of "under enemy eyes" route in a base and still be able to reach the objective.

If a player adds some contextual effect as doing this when the mission asks to go in and hack a computer or snatch a particular USB or something an employee only would have access too, then this would even add more value to the very fragile and "custom made" social stealth ...

I am wondering if the game allows to do something like this, if anyone tried to push the experience this far (it's nothing strange and incredible but can lead to some satisfactory immersive gameplay and ... why not, good videos and unforgettable story chunk experiences adding like this a part that unfortunately this game misses so badly: the ability to play clandestine and really covert ops if not clandestine that indeed in this game, especially the former (the clandestine ops) are guiltily absent from GR. (GRB in this case).
Especially in a game that could feature WD Legion repository or anyway that was designed to be a stranded\survival\low profile experience and thus should feature the "non violent" option...

I hope some will notice and give a feedback if they ever tried to do this. Or if not if anyone of you can try it.
see ya
