I hate the fact that Undead Night Elves are even in the picture. I’m not even a fan of nelves in general and I think blizz only spat on the wound when, on top of burning the tree (which, don’t get me wrong, I still think the whole place was an abomination, not lore-wise, in general, considering its history), they had valkyrs going anywhere near those who fell…
However, we’re way past the age of faction exclusive classes. Now, if we’re talking about aesthetics only, yes, it should 100% remain within the Horde.
They can still take the undead night elves and Calia while they’re at it, though.
I don’t think the Maw would be enough for someone like her…
