Still haven't seen a good reason to limit access to vendors for solo players. What harm was there to let people play solo, avoid PvP, or even strikes and raids? If someone is happy enough doing one thing why remove it? The weak argument about it would be an exploit to keep both is bad, just open the faction vendors to accept vanguard marks. Even if the Crucible vendor doesn't sell 1 item specifically for PvP, they could have kept that just for the awesome PvP godly players. Most of them don't like to share anyway by the replies they have been leaving.
