This will make too much sense so it will never happen. Get rid of Xur and transfer his duties of selling Exotic weapons and weapon upgrades to the gunsmith. You know the person who is supposed to work on wrapons. Then transfer his duties of selling exotic armor and armor upgrades to the special orders section. That way you can actually have those two do something worthwhile. As of now the armorer is pointless unless buying ammo packs. And special orders section contributes nothing of value. For all you oxygen theifs out there the gunsmith and special orders would follow the same time frame as Xur. Reading is obviously not fundamental for some of you.
