But as far as the story goes, we don’t have playable Helves yet. If we would have them, then Blizzard would have surely acknowledged it by now. What we got are Blood Elves customizations.
And as far as I remember the Velves are Belves.
Nothing indicates that these are Helves at the moment. I would love to read an official confirmation for this as well but we don’t have one. This is one of the things I also forgot to see when I got hyped about the Alliance finally getting some bone thrown at them.
