Seems to be completely gone but I may have just messed up. I actually didn't mind farming rare materials and have a bunch of them, but I seem to only be able to use them on myself. It would be nice if the Vanguard Quartermaster both bought AND sold spinmetal, relic iron, etc. And was there some kind of announcement about Commendations that I missed? I sure would have held off leveling up yesterday if I had known! :(
