Never say never. You even gave us a decent suggested Class that could simply have it as another spec. Rogues. With three specs that are basically the same, it would be nice to have at least one real stand alone. They wear leather, can dual-weild weapons (not to mention Illidan's own Warglaives) and wear Illidan's signature blindfold. Blizzard is already talking about ways to make the Rogue (and hunter) specs more unique.
