Ehum, okey? Good for you I guess. But seriously, there have been a Ogre Mug there for years, yet we havn't got any Playable Ogres. And again the same with the Halloween Masks, they most likely added a pair of other mugs to throw of the evidance of Vulperas Mugs. Also the arn't any Gilgoblin/Giblin/Kelfin mugs.
And I honestly don't believe in those slots, some of the races are either easy to make, such as the LFD and HMT, while others are fans have been asking for years, Mag'har and Zandalari. And again:
It wasn't a Blood Elf that took the "Blood Elf slot", it was a Night Elf. Nightbourne.
It wasn't a Night Elf that took the "Night Elf slot", it was a Blood Elf. Void Elf. How many times will I need to repeat this...
