Just to repeat it another way: Currently, all 3 Factions require Crucible Marks to buy gear. Yes, you can earn Faction [i]Rep[/i] in PvE, but to actually buy their gear requires Crucible Marks. Trading "destination mats" for Crucible Marks was a way to earn Crucible Marks via PvE content. By taking that away, we now have 5 PvP vendors—vendors who only accept currency exclusively earned via PvP. (And 2 Vanguard/PvE vendors, who only accept PvE currency.)
