I've seen a few people talking about how they don't like how they have to crouch in order to get the perk to work and want it changed back to it's previous requirement of getting a headshot kill while at full health. It's not a lot of people complaining, but a enough people to get a little annoyed. I feel like those people don't see the potential of this ability if used correctly. Now I don't know about you but I see the current version as much more useful overall. With how it is know you crouch and get a headshot kill, to go invisible and gain truesight for 9 seconds. As it is right now it can be used to get you out of dangerous situations or too stay invisible for very long amounts of time. Let's say you're being swarmed by enemies and you're about to die. In that situation all you need to do is crouch, get a headshot kill on an any add, and boom you're safe. You wouldn't be able to do that with the previous requirement. In fact you wouldn't be able to use the perk unless you were at a safe distance from the enemy which would make it more limiting. TL;DR It's perfectly fine as it is. You can crouch anytime, but you can't be at full health all the time. To those of us who do recognize the power of this perk, how many lost sectors/missions have you cleared with how being shot at. So far, I've cleared 4 lost sectors without being shot at out of the 6 I've tried.
