So I was driving home from work and came up with a fantastic idea. I am sure I am not the only one with ALOT of vanguard commendations and marks. So how about this idea. There should be an option to allow an upgrade to any primary legendary weapon with an elemental of choice (just one). Let it cost like 1000 Marks and require 20 commendations. This way we have something to use our "one of many" currencies we have in this game. Okay bungie... git er dun!
