We can buy weapon parts, so why not armour materials? I'm down to like 10 per character after all the infusing/levelling them up you expect us to do, so have to farm my ass off to get a few measly parts per strike/activity/whatever. That's if they dont change into motes of light! Please let us buy armour materials, possibly from the vanguard quartermaster/mentors or something :( Edit: I had to farm court of oryx with level 1 runes to get some armour materials to infuse/level up some Iron Banner armour and a pair of raid boots. This is ridiculous, I want to play the game, not grind for this sort of thing. I could have ranked my Warlock up to rank 5 in Iron Banner, but instead had to farm :S
