With the upcoming release of the World of Warcraft source book for 5E, are there any plans on releasing new sound sets for that setting?
Although Wizards are releasing the book the IP still belongs to Blizzard. So there are currently no plans for us to make official World of Warcraft SoundSets.
With over 1500 SoundSets in our catalog though, there should certainly be something to suit your adventures in Azeroth
