One way they could improve it, imo, would be to have traders only sell up to orange quality of any weapon or tool and to have all weapons found in loot to be worthless except to scrap them for parts. That way, you buy low quality weapons and use them or buy them to scrap them for their parts and anything you find would just be junk to be scrapped for parts and so all the high quality stuff would be only from crafting-- except the purple legendaries and those should only be rare finds in loot at a high enough lootstage that you would only find them in Tier 5 POIs in the wasteland and not given as rewards for quests by the trader.
That would be a pretty insta-download modlet if someone wanted to create it.
