Anything useful is better than just taking up space in inventory. I would be smitten it I could sell 20 materials for 10 marks. I was happy doing the same thing for 5 marks for 50. I would also be smitten to trade 200 material for 1 commendation. Every change Bungie makes seems to be against Guardians to acquire weapons and gear. It was painfully slow before but now it is excruciatingly painful. I guess all the posts begging to add MORE grinding won. Hope they are happy. What is next, locking out new strikes and raids until you complete dumb quests first? Wait, they added that already. I'm all out of dumb decisions to offer for now but I'm sure we'll see more in the next patch or two. I just haven't tortured myself enough with the grinding yet. They got to have a few tricks left to make it worse, right?
