Search your heart. You know it to be true. While players desire those special swords and armor with all the pluses you know that the stories they will tell will have nothing to do with those items. It will be the "useless" items if items are mentioned at all in the story. Because players like challenges. Nothing says a challenge like an item that isn't obviously useful. Those sorts of items are just asking for a crazy plan to show how clever one can be with a so called useless item.
