Yep, it sure is. Its an interesting one, as someone a while back in this thread did mention how it could make sense, if some Kul Tirans had bred with the Drust that were not hostile, that could explain the inhuman appearance of them.
Apart from that, Yep, calling Kul Tirans ‘Human’ is incorrect. Jaina is Kul Tiran. So is her mother. So is Flynn, They all look human. The Skinny ones are not biologically the same species as Humans in WoW, any more than a Dwarf is. It would be biologically impossible for them to contain the skeleton of a Human being. I’m not trying to be crass, but frankly they look like Concentration Camp victims. That’s not a healthy look, and there is no indication that Kul Tiras -starves- a vast amount of its population to look that way as state policy. Then on the other side of the scale, you have the beefier ones, who look like Andre the Giant. Know why they called him ‘Andre the Giant’? Because he was a Giant. Because he vastly exceeded the norms of his species in terms of size. Gigantism -isn’t- good for you either. It killed him in the end, and is a medical condition, not an evolutionary trait.
If one of the Beefy Kul Tirans had a skeleton of a normal human being, like say, Jaina, who -is- Kul Tiran, then they would not be able to walk.
So basically, the Skinny Kul Tirans are not Human, but some weird offshoot species with uber thin bones, and the Beefy Kul Tirans are not Human, but some weird…Thing, with bones much more similar to the skeletal structure of an Orc, possibly, as mentioned the result of Human/Drust inbreeding.
Either way, a biologist looking at the skeletons of the two types of Kul Tiran, and the Human skeleton, would class them as different Species…
We -Know- what High Elves look like. They are -already- in the game. Seriously, We know what they look like. Go to old Dalaran and look at the Silver Covenant, that is what High Elves look like.
