I would edit that statement's language though, how can blizzard have no idea what the races awere going to look like when they determine that?
Perhaps it's more accurate to say the moved away from that old concepts to this new glowy eye one.
I do prefer it when only Night elves had glowy eyes, and for me it would have been better if Thalassian elves had normal eyes, but the iris's glowed when they were using magic - and this was only the case with Thalassians and humans. Void elves I think have good justification for permanent glow. So do blood elves.
DKs should have glow
DHs should have glow
Nelves & nightborne should have glow
Belves should have glow (faint one though indicating low fel corruption)
But high elves should be normal.Worgen? - hmm, some, not all (few npcs, lock, druid, mage npcs mainly)
Forsaken? - few (priest npcs mainly -option available on CC for players though)
Draenei - normal
Pandaren normal
Human normal
Gnomes normal
Goblins normal
Dwarves normal
Trolls normal
Zandalari normal
Dark Iron normal
Mechagnome normal
Humans and Helves should have glowing irises when using magic
Draenei should get full eye glow when using magic
