My instincts were right. I just knew there would be a Darkmoon Faire overhaul in the near future! Those faire balloons that were datamined in the previous patch just screamed: "keep an eye out for me, update coming soon!"
If you haven't heard already, in the next patch (4.3), the Darkmoon Faire is getting revamped. New quests, activities, tickets, and even location. But the biggest news? NEW PET(s)!
So far Blizzard has revealed only one possible new pet, a "fez-wearing monkey" that will be available for purchase with new faire tickets. It may also require some level of reputation with the carnies. There may be other prerequisites for any other companions that are added to the faire, but we'll just have to wait to find out more.
I can't wait to test all of this out on the PTR! If a certain reputation is necessary, I may have some trouble thoroughly testing it, though. I knew I should have turned in more tickets and items to raise my rep, but I kept putting it off. Well, it's come back to bite me in the butt now lol. Now I can only hope that it will at least be interesting and fun grinding out the rep with the updated Darkmoon Faire.
In any case, I'm definitely eager and anxious to discover more!
