I think a lot of folks have been spoiled over the years with having the ability to enchant items. Unique items were always what drove many an adventure in D&D and the older D&D computer games (SSI games, Baldur's Gates, etc). Usually only a renowned mage would be able to enchant an item. . . but lately it seems Joe the Thief can enchant anything he wants assuming he has the materials. It takes away from the allure of truly bad ass treasure.
