I suspect they couldn't make it easier to get materials and still have materials traded for marks. It's make it too easy/quick to get those crucible marks I guess. It just sucks that now all those PVP items on virtually all the vendors in the Tower are only there for people who PVP now. If there is any question as to whether this is a PVP game or a PVE game, look at the number of vendors in the tower that require crucible marks for wepaons/armor and those that require vanguard marks for weapons/armor. It's not right. It should be a PVE game with PVP tacked on. Not the other way around.
