I like WoW, but every customization and advancement they have added is just "tacked on" to the old game. They can't even figure out how to make every skin color available with every face. I don't think they are changing skin color the way FFXIV dose. It's like they were creating a new face for every combination and just ran out of time. They are only recently making skirts where legs exist, kind of. And their physics are... sad. FFXIV may be behind the times, but it's far ahead of WoW on most things.
They have no body customizations that changes the shape of the model, other than Orc slouching I suppose.
EDIT: Dracthyr have some minor body shape options, but they are also very limited in what they can wear in dragon form.
