Your response has good points. I enjoy the vault of glass but, with exception of the pretorian foil, have received every vault armor and weapon drop relating to my characters. That being said I'd probably continue doing the vog for the slim chance of exotic drops and the enjoyment of chuckling through with friends and randoms alike. The vog more so than Crota' raid has a massive feel to the environment. I would hate to see it become obsolete due to level progression. It would be cool to see the developers do something more with it to keep it relevant.
