Just come back to Destiny now the expansion is out and i have lost a load of vanguard marks I had been saving not realising this had changed. Went to trade in my spinmetal and suddenly find myself with 90 spinmetal and next to no marks left. This should have been made so much clearer, I had no idea and as this is all online I can't undo what's happened. I don't even farm them, just pick up when I see them during play. Put me right off playing now as its left a sour taste in my mouth. :(
