I would say it’s a bit disappointing yeah, but at the same time, expected. I lowered my expectations a while ago. Best we can hope for is that, somehow, we get to keep Venthyr abilities, or have them turned into a toy, of sorts. Those would be awesome for a perma-San’layn use.
One benefit though is that (I know I keep saying this) we now actually have a foothold, when we had 0 argument before, ever, because we simply could not play any variant of undead elf. Now, however, we can at least suggest and argue for expansion of this customization.
After all the obvious things (unpairing skins and eyes, letting DKs use it, giving it to nightborne), I think claw and fang options would be the next awesome step. Neither of those things seem incredibly complicated to ask for.
As for vampyr lore, I really hope they expand it. I imagine they might in Northrend–as it was emphasized twice that something is going on there. Perhaps in the prepatch. Really hoping the lore is solid for these folks, it’s the lore I really fell in love with in the first place.
