While I understand where you are coming from with the "more content" perspective (having all VoG weapons at 331 = more guns to choose from), this would be a fundamental flaw in the classic yet effective RPG progression system. The fix to this is not to make all VOG weapons 331. They decided to go a different route and provide the player with gear and guns by other means (vendors). This created a problem in that it makes VoG essentially useless to run (besides getting Fatebringer, Hail Fatebringer). But just like any RPG, the content doesn't go away when the gear is obsolete. I run VOG just for fun. But Tier 1 gear should not be equivalent to Tier 2 gear etc. TL;DR: Learn to let go. Run old content for fun, not progression
