Blizzard has taken to the official World of Warcraft forums to comment on the reported WoW Classic Layering abuse.

Since Classic’s launch last week, there have been various reports of players being able to swap the newly introduced layers at will, which could affect Classic’s economy and other aspects of the game. Players have suggested that a few people were able to exploit the layer system in order to farm thousands of materials, but according to Blizzard, this isn’t the case and even the most-popular Classic realms don’t have enough layers to pull this off.
