I agree with you to an extent. I don't know if you've played Halo 5 or know much about the multiplayer, but they have requisition packs you can buy with req points that you earn through playing mp that unlock aesthetic gear and weapon skins, etc. or you can buy them with real money. What I like about it is that you can still earn them by playing if you don't want to spend money. So if BungieVision were to ever start selling shaders, which I'm sure they will, I hope they take that same route: let the people with money and no patience buy them, while everyone else can try to get one from a drop.
