Not giving up hope for San’layn as an Allied Race.
But again if that’s not meant to be, I hope Blizzard considers this:
A Night-Warrior-Like Questline in which you’d get the following features on a Thalassian Elf:
-Bat-like Ears
-Red/Black/Amber eyes
-Claws
-Fangs
The questline would explore:
-How the San’layn joined the Horde, likely a splinter faction
-The origins of the vampyr curse, if not explained in the upcoming lore, and how to turn someone into a vampyr.
Note: This could technically be applied to humans as well and grant the Alliance human vampyr, in which the questline would need to explain how they’d be allowed on the Alliance. Not too much of a stretch considering undead night elf customization might (?) be on the table for alliance night elves.
