I know that Ogres don't have a female version as of now, but how hard is it to create that?
And the argument made for Ogres being fat and ugly, no one would play them... yet the same can be said for Kul Tirans, they are one of the lowest subrace choice played. Barely beating Mechagnomes.
Ogres also have a vast amount of culture and history within World of Warcraft, they have been part of the franchise as early as Warcraft 1. They have a good amount of noteable lore characters such as Cho'gall, Dentarg, Mogor.
But I guess we could use one more variation of Elf I suppose.
