I don't think the parroting technique, of changing the words in the original quote and repeating them back quite work here because you are completely wrong. It only works if you are right or have a more substantive point to make.
Firstly, Void Elves do sprout tentacles. Plenty of them have tentacles interwoven with their hairstyles. No Blood Elves have tentacles interwoven into their hairstyle and any Void Elf in any class they can play can have the tentacles.
Skin tone is a far more extreme change than eye colour. Elves manifest the magic they are feeding on through the glow in their eyes. When they fed on an Arcane Sunwell, the glint was blue. When they were exposed to substantial amounts of fel energy, it shifted to green. Now that the Sunwell is a font of holy and arcane energies, some Blod Elves are beginning to manifest golden eyes.
Skin tone shifts only occur with more profound transformations, such as into Felbood Elves or into Void Elves. To equate a natural reaction of a thalassian elf to a magic source with a skin tone shift only seen after much more profound transformations is another false equivalence unsupported by lore, peddled in an attempt to support a blatant falsehood;that blood elves = high elves = void elves.
This is demonstrably incorrect.
