Looks almost like a Night Elf, but her Body is to skinny/elegant for it, also no big/long eyebrows, her hair is also only avaible for Blood Elf, called Raquel.
The Weapon she hold is the Legendary Weapon Thunderfury, Blessed Blade of the Windseeker.
In the Background we see something like a Fel Reaver.
Could be also a Warrior but with her blindness its more likely a Demon Hunter + Leather Set at least shes holding her Backweapon with magic.
