Whats NPE?"the NPE gang".
I can see the challange in that Delaque will have their turn off the lights and use photo goggles/infra sights.
However I dissagree that its a tax for other gangs to get the same equipment to counter pitch black as they are usefull for other things besides that. For example Smoke.
I really look forward to how and what the different psychic disciplines are. We might even see a soft errata on how psychic powers works.
As for Nacht-Ghouls I see them as kill-that-guy-specifically and a way to mess with gunlines/really dug in gangs. Since you wont have the backup of the rest of your gabg if you spring them to soon.
