I have an idea for improving the shader system. First off, they shouldn't be consumable. You should unlock them just like armor mods. Then, once you have them, you should have to spend a certain amount of glimmer or some other resource to apply them. I think this would make people with exclusive shaders fell less inclined to never use them and would fit in with Armor 2.0. Plus, it would make it easier to make your entire loadout look seamless colorwise. Those are just my thoughts.
