the vast, overwheming majority of Destiny players have not run the Raid every week since release.
of both those who have and those who have not, a majority do not have all of the exotics.
more than three-quarters of the exotics are nowhere close to garbage. the suros regime in particular still remains one of the best ARs in the game.
any new or duplicate exotics that drop will be at the new base Attack rating, potentially saving on future upgrades.
for the immediate future, the VoG primaries will remain incredibly useful in a variety of content, most likely including but not limited to the new raid. In particular: Fatebringer, Vision of Confluence, Praetorian Foil and the Vex Mythoclast.
The lower barrier of entry (26) means it remains a viable avenue of progression for the many players that are still below level 28 on one or more characters. Different combinations of new vendor legendaries + VoG gear along with exotics will offer a variety of onramps to 31.
Level 30 is about to become roughly as easy to hit as level 28 used to be; I will begin at some point in the next few weeks running weekly VoG Hard runs for those who have not yet had the chance or have had trouble getting through so far.
