Novocrane : If you take the Vision Enhancement table and say "everything in here isn't compatible with Hawk Eye", then there is a huge problem. Image link - which is the basic component of HUD and AR - is in that list, and it is, in my opinion, as much vision enhancement as Smartlink, if it isn't more. By your logic, it would mean that anyone with the Hawk Eye quality would be unable to use lens or glasses with image link, meaning they would have absolutely no access to a HUD or AR.
Sorry if this sounds rude, but to me, this is the direct implication of what you are saying, and if it was supposed to be read the way you say, I don't see how it should be a positive quality.
