I dunno if they were ever shared (I might have lost them), but an official preview was released by an Italian outlet containing some of the dungeon maps. Hope they are useful!
Seeing that with the books they are focusing on the existing WoW classes, one of my future players is asking if he can attempt to play an artificer and they are well inserted in the lore...
How would you adapt Artificers in WoW?
How would you name the class, the subclasses, and which subclasses (from the 5.5e Eberron source manual or the Reanimator)? How would you reflavor them? Which races do you think are the most suited, aside from gnomes/mechagnomes?
