Not only should they stock the old weapons, but have them cycle the perks too. Since the dlc dropped, the new weapons seem really stale. I love HCs, but the TDYD is just awful for pve considering it's a vanguard weapon. (I only play crucible for exotic bounties) I mean, I lucked out and got a random drop of Red Hand IX and TFWPKY 1969, but that shouldn't be the only way to acquire better weapons. If the older models can randomly drop with tier 2 damage, there's no reason they can't be cycled into the vendor stock too. I just miss my TDYK.
