The tower vendors should offer a legendary upgrade path (crafting) for all game items to current tower-comparable stats with RNG perks each upgrade. It would add to variety of character builds so we don't all look the same and keep the vendors relevant, and finally a use for the ever growing piles of commendations and ascendant materials....win/win/win It could be implemented exactly like the way Xur upgrades exotics. Say you want that L1 Khostov in your vault to be legendary. Take it along with a commendation, some glimmer to the gunsmith, he makes it uncommon (green background) same to get it to blue background, to jump to purple, same except for going to vanguard/crucible/faction vendor with some ascendant materials/glimmer and say do a special always-available bounty to get your item to purple background. Please bump/like if you agree.
