Seriously, it's a quality of life issue at this point. Shaders. Exotic weapons.
[Edit]
I'm not saying to replace the ornaments with shaders outright. There's a lot of ornaments that provide weapons with aesthetic structural differences that I would love to keep. But we can't make those great ornaments match our characters without the appropriate shaders.

They should make exotic shaders, make them unique and animated and only for exotic weapons and armor.
