That is true, but I don't think many of the weapons in Destiny that are considered "top-tier" are faction weapons. The Vanguard Quartermaster sells Shadow Price, The Devil You Know, The Comedian, LIGHT/Beware and THE SWARM, all of which don't require PvP. You get some of the best weapons in the game (Fatebringer, Vision of Confluence, Found Verdict, Atheon's Epilogue, Corrective Measure) in the Raid, which doesn't require PvP. Even more so, you have a very high possibility of getting a faction weapon/armor through reputation gains, which are rewarded in high amounts via the Weekly and Nightfall events (which are PvE). Not saying it shouldn't be looked at, but it certainly isn't as big an issue that OP is making it. Most rewards come in bigger quantities and better qualities from PvE.
