That's the bigger problem than weight though. Male Kul Tirans have personality which comes from that gruffness, the female models just look entirely devoid of personality. They look like the human models but with the weight tweaked, not like their own independent race and personality like the men look.
For all the people complaining about people complaining about the weight - It's Blizzard who'll never commit to the idea, and even have to try and make trolls and orcs fit normal beauty standards. The female Kul Tiran is boring, because Blizzard don't have the balls to do something aactually different.
