Would You Use Insidious If It Had This Feature?
Insidious is a simple perk that does what it says it does; once you stand still for a certain amount of time, you become undetectable.
Though this perk stops having use once you realize that time standing still and setting up plays with it is time that is not spend putting pressure on survivors. When you do this, you risk not finding anyone at all to surprise. This makes an otherwise wacky and fun perk pretty rare to see.
When paired with Whispers, Surveillance, or other perks of the type, it can help you better set up plays. But that's two perk slots for a build that may not even get any use.
I think a small addition to Insidious would make it more viable, or at least a little less costly to use. It would act both as a stealth and minor detection perk.
When you become undetectable via Insidious, you can see the aura of all survivors within a 10/12/14 meter radius.
Would you use this perk in a build if it had just a bit more information with it?
