A bit of a thought of mine..
You know the elevators in UC?
You know how, back before you had things like flying mounts and vrykul horns, Taurens were the only ones who could get stuck on em?
You know how, often, when a Tauren would get stuck on em, if they insisted on trying to enter on a mount, they would fall to their death?
You know how it could take a while to retrieve your corpse, as you had to wait for it to come back up?
I SWEAR the undead were using the elevators as a steak-trap to feed their entire race, and claim innocence.
