“Today, the goblins of Bilgewater Cartel are introducing a new way to use the WoW Token. Now, when you choose to get a WoW token from the Auction House, you can decide if you want to convert it to 30 days of game time OR Battle.net balance. That’s right – Battle.net balance to buy services like World of Warcraft character transfers, digital pets and mounts, or purchase in-game items for other supported Blizzard games you play.”
In other words, you can farm gold in WoW, use it to buy a Token from someone else (who paid real cash for it), and then choose to redeem it for the 30 days of gametime or $15 in Battlenet currency, which you can then spend on anything for sale on Battlenet, including character transfers and loot in Blizz’s other games.
The change is retroactive, so if you’ve got tokens lying around, you can turn them into murloc plushies straightaway. As it should be.
