If you can manage to get to Tharbek's side of the balcony in the new dungeon (It's fairly simple, jump from one ledge to another and follow it along the wall to the other side of the room) you can pull a level 101 ogre (http://www.wowhead.com/npc=76599) and a few dogs from the hall behind the balcony area. They have a chance to drop The Joy of Draenor Cooking - Item - World of Warcraft and a few greens ilevel 580-593.
I originally posted about getting to the other balcony in the exploration section, but this discovery sounds more like an exploit to me. Not sure on the drop-rate but it dropped for a random dude the first time we killed it, but he outrolled me. Killed the ogre again with my guild and had no such luck :\
EDIT:
Thanks to Billsteh for pointing out that this actually grants access to the entirety of the dungeon.
And to Xelun for providing a how-to: http://imgur.com/a/BWCSITaking this one step further, if you charge to the orge you can get through the gate. From there you can do the rest of the instance which is not scaled down. Ragewing oneshotted me but presumably if you can kill the last two bosses they should drop WoD loot.
