The last I did that I got 5 marks for 50 materials. Sure, the exchange rate sucked though. That is exactly why that option should've been improved. Not removed. And trading excess vanguard marks you can only use for pretty much one set of gear from the vanguards, to buy materials that you could've then exchanged for crucible marks would've been a significant improvement in itself. And if it was "totally useless" and you'd never do it, why are you GLAD they got rid of it? What negative impact did said "useless" option have on your game? I guess you're one of those people who get some enjoyment every time another players get a more negative experience... What a great attitude to have. The overall "gaming community" these days.. SMH
