I just came up with an idea.... I think if you [b]FULLY UPGRADE[/b] an Exotic Armor or Weapons piece of gear, it should appear differently. I don't know.... as an example, a Gjallarhorn will glow and a non fully upgraded one won't glow. It'll only start glowing once its done being upgraded etc, etc. Im not saying all Exotics should glow, maybe they could all have a unique cosmetic special effect to them. Maybe the Heart of Praxic Fire (Warlock check piece) could have floating flame hearts coming out of it, similar to the Halo: Reach Armor Effect, Heart Attack. I can see this cosmetic add-on to Destiny make people want to grind more for Exotic upgrades. Tell me what you think, good or bad?
