So according to the interview with Morgan Day and Shani Edwards on MMORPG dot com, it was mentioned that the heritage armor sets for worgen and goblins will be landing at the same time as the model upgrades.
I lack the posting count to have permission to include links in my posts but the article on there is titled “New World of Warcraft 8.2 Info: Tyrande, Sylvanas, Customization, OH MY!” for those who want to go have a look themselves. Here’s a quote, though:
"Goblin and Worgen fans will be pleased to hear that the long-awaited model update for each will be arriving in a future content patch.
“Shortly after Rise of Azshara, you’ll see that,” Morgan explained. “These are the two races that haven’t been updated. They’ll have new heritage armor with that as well.”
Is this still going to be the case? I ask because there was no mention of this in the development notes for the 8.2.5 PTR. Can we get some blue confirmation as to whether or not those plans have changed?
