I believe that, right now, they believe that most of the negative feedback for Wuk Lamat are from the "loud minority" since they mostly ignore the forum and listen to content creators and twitter users. And since people on Twitter are quite positive towards Wuk Lamat, I believe that she will still play a major role up until or beyond the next expansion, acting as a new member of Scion and leaving Tural to Koana when she goes on adventure with the scion. Furthermore, since now "a threat to the world is a threat to Tural", we might see Wuk more often than we think.
