I apologise for my mistake in referring to the Legion x11 but I appreciate your reply. Here is the detail information of the issue.

Rensar Greathoof is the one who gives the starting quest for each artifact weapon. The quest from him to choose a weapon should look similar to this but it only gave a single choice of the Fangs of Ashamane for Feral druids which is the quest of The Shrine of Ashamane. The quest I would need to begin the artifact weapon quest for Guardian Druid is Mistress of the Claw which awards the Claws of Ursoc. If you need any additional information please let me know. Thank you again!
