Any chance we could get the option to buy Weapon Parts directly from the Gunsmith? Being able to spend Glimmer, or Marks like we can for other upgrade materials, would help tremendously. The class specific armor upgrade material, Sapphire Wire, Hadronic Essence, and Plasteel Plating, is an issue for many players as well, and being able buy these things would also be a welcome addition to the game economy. Probably the Vanguard mentors would be a good place to trade Glimmer or Marks for these materials.
