Armor Designs
One of the issues that constantly comes up with Destiny is the armor situation. While the armor available in the game certainly looks cool, you will often see most people wearing the same thing. It’s not that they’re unoriginal, it’s just that it happens to be the most useful stuff in the game. The modding community could certainly help out in this regard.
Whether as brand new, fully functional armor, or just skin overlays, modding can take Guardian appearances to the next level. Unique armor sets brimming with the lore of the universe that Bungie has created would be a more than welcome edition. Riding into battle on your combat Sparrow decked out in gear forged in the depths of some unnamed planet, or experiencing battle with new armor abilities would definitely help strengthen the RPG side of Destiny.
