So I have found that over the course of the game, as I get better at enchanting, it is usually more worthwhile to personally enchant things versus getting 'fancy quest loot'. I routinely find that my own personal enchantments outstrip what is supposed to be worthwhile gear. With such awesome looking reward armor like the Nightingale set, it is annoying that my personally enchanted Dragonscale armor makes the reward seem like a silly waste of time, despite how incredible it looks.
That all being said, my request is pretty basic. I'd like to have a way to remove or improve the lesser enchantments (kind of like how in Smithing you can improve armor quality). As an alternative, having sets of blank gear to personally enchant is also acceptable, but the former would be much cooler and useful!
