Ayoola certainly looks like a typical aiel, caucasian with red hair, Scandinavian appearance, she's got that in spades.

Who the hell is casting these people? Is there an opposite bias going on?

Having read the series it's not possible for me to even accept this made up by the screen writers BS. I can't accept Perrin being married. Or killing a wife he never had. He never even had a beard. And what happened to Master Luhan? They start the tv series with lies they're going to have to keep on lying about and make even bigger lies about for the rest of the show. Are they going to write Faile Bashere, Perrins future wife, right out of the whole thing? Faile is a huge part of the series.
