People wanted Vrykul, honestly. Or, they would've been more interesting, at least. But just like they got a poor man's High elf, they get a poor man's Vrykul. Also, honestly, the female Kul Tirans just don't look good. Nor do the male ones, particularly, as far as I'm concerned. If you just want to play a big character, you already have options on Alliance. Now you have another. Nobody cares.
