[b]Vanguard and Crucible vendors should have their inventories re-roll every one or two days to sell weapons and armor from Dark Below and pre-DB. These weapons and armor should also be drops in engrams and rank up packages.[/b]
We had no idea that etheric light and the ascension system would be added so we figured that our old weapons and armor were useless when Dark Below came out. I had some really good weapons that just became obsolete once DB came out and it would be nice for them to be added back in.
And of course with the addition of all these armor pieces and weapons we would need more vault space.
