Inner Town Base Camp

Once the Birth Mothers had left, Jin had begun to look at the status of the Pillar Base Camp. It was already morning and the Pandarens were coming into the raid instance via waves. Because of the proximity of the base camp to the teleportation crystal near the third layer of the Inner Wall, the teleportation crystal was used instead mainly to give the Pandarens the 'excitement' of parachuting down from above. 

While the dungeon supplier could have made it easy for the Pandarens and teleported them into the Pillar Base Camp, he purposely created this 'situation' so that he could 'milk' the Pandarens who failed to jump onto the pillar and descend. But he had a valid reason to do so as well. The third layer of the Inner Wall requires reinforcements as well and if they could manage to clear it, the Pandarens would have a safe base of operations they could use.
