Yeah that's what I was thinking, still too early tho and since in the official preview the Blood Elves have the non-teal blue eyes it could just be WIP they don't have it atm.
It does look funny tho cuz it comes off as Blizzard going 'MUST.NOT.GIVE.BLUE.EYES.' as if there's a certain sect on the time not wanting it done lol

Still too early to tell. The new skins for instance aren't in this build I believe. There's still many months before Shadowlands is out and thus much time to see whether or not certain cosmetic options are happening or not.
