No Asian has a long pointy nose like that. The eyes aren't a typical east Asian person's eyes, either. He really looks like a White guy with long dark hair. So why did Blizzard only make an Asian female and White male wizard but keep all the other races' ethnicities consistent?
Asian itself is a rather broad term. You're just complaing that he doesn't look slanty eyed enough and, "talks rike this".
I mean, are you really gonna examine the features of his face and tell us he's not Asian? I'd feel pretty silly trying to do that.
