Astute World of Warcraft players noticed that the 5.4 patch brought with it an interesting new addition to the public test realm. A few players on the forum noted the sudden appearance of an XP buff item, which appears to be sold through the same cash shop as the mounts and pets currently available. The item, an Enduring Elixer of Wisdom, grants 100% exp bonus with no mention of how long it lasts.
Community Manager Zarhym chimed in later in the thread, confirming the item and explaining that Blizzard is exploring microtransactions.
We are currently exploring the possibility of adding a way for players in certain regions to make purchases directly within the game. As part of this process, elements related to this will be appearing on the PTR. We’ll provide additional updates on our plans as development progresses.
Whether or not Blizzard decides to go ahead with fully implementing a cash shop will have to be seen.
