I for one have 3. To race change my main to a female void elf, create a second hunter on my main realm (thank you 6 more character slots <3) that's a male void elf, then I want a female nightborne hunter, if I ever decide on a Horde realm to play on.
I've even used wowhead's dressing room to give preliminary looks for them: (may change by the time they're released, just stuck the same transmog as my main on the Nightborne as I have no idea what transmog I'll use for her, though I now realize I forgot the belt in the Void Elf Female pic, but have it in the Nightborne one, haha)
