No, it isn't. Paradoxically Void Elves, far from being the trojan horse you insist they are, prove you wrong. Because Void Elves had to have everything else done to them, the skin tone changes, the hair colour change, the new hair styles, the new facial hair options, the new racials, the new lore, all of that had to be done before they were made available to the Alliance using the standard thalassian model. If you were right and silhouette and animation was all that mattered, and political opinion was irrelevant, they'd have just given you Alliance High Elves.
