Raids are supposed to be divided into teirs. Each new one released give better rewards thant he previous. VoG should be left as is. What Bungie needs to change is how they implement the new raids. Your armor and weapons from the old raid should still be valuable in the new one, unlike what they did with the Crotas End implementation. Completely demolishing any armor and weapons from the previous tier is the problem not making the new weapons and armor better.
