Well, when a human female spends all of her day running across a forest or a field, or through a mountain on foot instead of sitting in a chair all day or running for 30 minutes a day, and the common citizen in Azeroth doesn't take gryphons or own a Gnomish vehicle, and they do not go by a diet of processed foods, then yes that is generally what the human female body is supposed to look like, give or take some on breast size.
And about the jokes about getting nails done and knowing tailoring/cooking, that's why in the emote is says <name> tells a joke...because it's a joke. She needs to grow up and get over it.
