I want enchants for all my heirloom items, dammit. Enchants that scale with level like the items do. And hell, whilst they're at it, they can make them automatically give a bonus to the best stat for the class and spec.
Make them hard to get and even make the mats unbelievably stupid, or even unique so that they'll always be difficult to get even when WoW is up to 1,000th-level characters, but dammit, just give them to me NOW!
