I have a great idea for farming planet materials. Maybe a smartphone app, that you can farm the materials from planet (spinmetal, relic iron etc...) to planet while you are logged off of destiny maybe you are on the bus coming home from work or whatever. Have some free time and need extra materials? great way to stack up on materials. Should not be as effective as actually loading up a patrol mission and actually being on the game, but it could get the job done and it is a good idea in my opinion!
