Why anyone would quit because of this mind boggles me. Trading in 50 materials for 5 marks is absurd I would never do that. Basically you would rather farm for material then play the game to get marks lmfao. Just do the daily story and bounties and weeklies and that will max your vanguard marks for the week. I never do strike playlist. 1 pvp match will get you 5-7 marks that's way better then trading 50 materials for 5 crucible marks.
