I harvest rares in order to craft MC items that I then salvage / break down for infusers or to planar level my weapons. In a production mode, I can craft 100 or so items at a time. My rares stack, my infusers stack...but the crafted items do not. And you have to break each piece down one at a time. It can get tedious. Especially if you've made a lot of them. Can the game (DBC) make it possible for crafted items of the same type to be stackable? And salvageable in the same stack?
