Watching the trailers and ViDocs, I couldn't help but notice that Bungie had apparently changed the upgrade system for Weapons and Armor. My question is why; why fix what isn't broken? The system HoW introduced was exactly what everybody had been asking for, it was almost perfect. Etheric Light, the new Upgrade trees, etc. Why change it? Almost everybody was satisfied with it. Why go to all the trouble of fixing so much if you're just going to turn around and tear down all the fixes after 3-4 months?
