Planet Material- -How about instead of planet material, it gets changed into essence to then be used to upgrade gear? This way it can combine our planet materials into a single item.....or we can simply exchange our planet materials into that new single item? Unique guns- -How about have a mission from the cryptarch or Xur? Our reward would be a legendary or exotic gear piece with a perk such as a 10% chance to have a legendary item drop or a 5% chance to earn extra coins? Sparrows- -Why not look into a lot of those fan made sparrows and make skins that are based off Exotics, or even based off enemy types as well that would be cool, maybe even upgrade our stats and perks on sparrows making it go faster or handle better or weather we want the boost perk that explodes over time or a normal booster and so on.... HUD screen- -Where we see our super charges and ability charges, why not have the option if we want to display our countdown timers on them or not like in Overwatch?
