We really need shaders for exotic weapons. Honestly, we already can put shaders on exotic armor pieces, ships, sparrows, and ghosts. It'd only make sense to add it to weapons. Not to mention the possibilities of cool looks (or horrific looks too LOL) that you could pull off. For example, if you have the New Age Black Armory shader, you can replicate the Outbreak Prime look for the Outbreak Perfected. I found that out personally after trying on the New Age Black Armory shader to see how it looked on my armor. I happened to have my favorite exotic Outbreak Perfected on at the time and by chance noticed that I was looking at the Outbreak Prime. It'd be beneficial anyways, because it could draw in more people for having the ability to further customize your exotic gear besides just ornaments.
