Some of those seem only good as quick temp uses. And since you can switch them up on the fly, it just becomes a tiresome menu exercise.
Such as: Advanced Weaponry Makes advanced weapons available for purchase to the player at the weapons vendor located in the Security Wing.
Well I don't need that perk out in the field, so when back at my BoO, I have to go into my perks, turn this on, check for anything good, go back into perks menu, switch it out, then back out into the city. There are others like Stat Switch, Division Tech Materials and Clothes Vendor.
I hope they realize this and make these perks passive and just on by default, to streamline gameplay.
Perks are passive. Once you unlock them, they're active permanently.
