Shaders limit player expression because you can only pick from the color combinations Bungie has made available. The recent eververse shaders all feature special effects/textures, because Bungie thinks players would not buy shaders without them. And so, I hope Bungie understands that there's only so many shaders you can make in an 8 year-old game and that they should either get rid of them in favor of a color picker, or introduce custom shaders: shaders merged from other shaders you own.
