Some stealth abilities should ignore the “Revealed” debuff, mostly considering utilties with long cooldowns and traits, such as Blinding Powder and Instinctual Response. It’s really aggravating when you use one of these utilities or one of these traits kick in, but they fail with “IMMUNE” because you had 0.01 seconds left of revealed.
I personally would be in favor of a revealed rework entirely, in my personal opinion, revealed should subtract your stealth time by it’s remaining duration, if tweaked a bit, you wouldn’t be able to spam stealth skills, but at the same time it would be much more tolerable.
