Not exactly good logic, there. A less bulky Dunmer doesn't automatically rule out body sliders. I also don't get why everyone is of the opinion that TES elves have to be all slender or can't get bulky.
Doesn't rule it out, no. But it doesn't make a good case for body sliders if every Race shown follows only exactly what the lore stereotypes them as. And it's not our "opinion" it's just the history of the game has shown that Orcs/Nords tall bulky, Wood Elves short and slender, and Everybody else in between. Then you have generalized fantasy versions of elves, who are almost always slender, occasionally tall, and then you have folkloric elves who are really interchangable with dwarves, fairies, etc, being diminutive to the point of hiding under mushrooms etc.
