If this is the case then something is seriously bugged or at least inconsistent. I did some testing regarding this a while back so see what exactly would happen if you triggered CI while disguised.
The way I tested it was I had my friend who I was talking to on VOIP be on the other team. As an operative I’d steal a uniform from a teammate of his far from where he currently was. What happened then is I would immediately appear on his radar regardless of how far away from him I was because I was now considered a friendly. There was no way for me to leave his radar too.
So, since I was on the radar, when I snuck up on him without him seeing me I would never once trigger Combat Intuition. This was tested many times always with the same result.
Having said that, I’ve experienced a lot of strange things happening in games regarding Combat Intuition. Like having what appears to be a covert ops trigger my combat intuition which should be impossible. Also I’ve had situations where my combat intuition is triggered so I spin around only to see a wall behind me with no possible way for an enemy to have been there. This seems to happen most often when I’m in disguise. I’m starting to wonder if CI strangeness has to do with laggy players not immediately showing up on the radar, which would trigger CI then.
It would be nice to have a dev confirm how it’s intended to work while disguised since there’s a lot of confusion.
