CORRECTION: Wrongly thought a reference to Ronda Rousey. The NPC is in honor to Rhonda Cox (Associate Producer at Blizzard Entertainment on the World of Warcraft Sound Design, Music & Voice Over Team) as stated by her here.
While playing the Monk Artifact Questline taking you back to the Wandering Isle at level 100, I stumbled upon a human monk named Rhonda. It struck me as an easter egg for those who watch UFC. XD
Ronda Rousey is currently ranked the #2 female bantamweight fighter in the world. You can read more about her career here.
