I'm sure Bungle has "Top Men" working on it. Likely the hold up is figuring out an easy way (for them) to monetize this so that you have to jump though a tonne of hoops (i.e extending your play time via Bounties and running hundreds of Strikes, Crucible or Gambit matches) using only existing assets and then once a Season you will earn the Right to change your Guardian appearance - within Gender Fluent Non -blam!- limits enforced by Bungle - for Silver.
