Why can't it rotate??? At least rotate the damage types on weapons where applicable at Vendors, maybe weekly (solar/arc/void weeks along with weekly reset). Also, Why not make Rare DLC guns available for purchase at vendors ? We paid for DLC - seems like they should be available on a rotating basis at the gunsmith for glimmer and/or other vendors for the currency they deal in (marks) - set up a DLC gunsmith if need be. If nothing else just for variety sake.... I have every exotic weapon except Necro and a bursting inventory of legendaries - sometimes it's fun to take a rare and do a quick upgrade on it, mess around with it for a while and dispose.
