While looking through all the tasty new datamined stuff - I came across the Darkmoon Rabbit pet. I smiled and thought nothing of it... figuring it was just a new pet being added to DMF...
...but then I saw the achievment.
That Rabbit's Dynamite!
Slay the ferocious Darkmoon Rabbit.
OK - now, either this is just an exaggeration - where you find a little critter rabbit in DMF, slay it, and get a pet...
...or is it possible that, through the obvious Holy Grail reference, that they MAYBE did add a Darkmoon Faire mini "world" boss that randomly appears!?
It would be a riot if you needed a 5 man team to kill him. Since it is an achieve I'm kinda thinking you might - although it could still be a normal achieve for it being a rare-spawn.
What say you all?
