"Destiny is so PVP heavy. Why can't the factions be opened up to PVE players?" It WASN'T made clear. And it is 100% open to PvE-only players like myself; go grab their mark and do Vanguard Rep for the Rep half, and go grab spare resources and turn it into the Crucible Quartermaster for both Crucible Marks and Rep (which can still be converted over to FWC/DO/NM Rep). You can alternatively turn that into the Vanguard Quartermaster for Vanguard Marks and Rep.

This!! Talk about evading the question....

Exactly! You knew what he was asking, why do ALL factions but vanguard require crucible marks. You just avoided the question....

^This^ DeeJ, you know full well that was the question being asked.
