Warlords of Draenor changed the disenchanting rules (again). But more importantly, I’ve stopped getting much use out of this gizmo myself. At some point, it just got to saying, “Disenchant gear from expansion X to get enchanting reagents from expansion X,” and one doesn’t really need an addon to know that.
Also, I’m a much busier goblin than I used to be… and I don’t have an army of code monkeys at my disposal. (Besides, according to my cousin Rob from Booty Bay, although they’re very diligent, their output stinks.) So I focus my efforts on products that my most frequent testers (that is, myself and the employees of Fizzwidget Industries) actually use frequently.
For an alternative, see Enchantrix from the Auctioneer suite.
