Even with the increased manpower in the Pillar Base Camp, there was still no progress as expected. The rank and file Demon Rats that were surrounding the Pillar Base Camp were still numerous and they were 'refilling' at a rate that even the increased numbers of Pandarens could not take on.
It was pretty obvious that the Demon Rats had already begun to know that the Pandarens were more or less stuck in the Pillar Base Camp unless there were sacrifices willing to push through and break the encirclement.
And that itself would still be an insurmountable task to perform. Unlike the previous time when the Demon Rats consisted of a mix of melee and ranged troops, now they were playing with guns. Almost every one of them was hiding behind a piece of cover shooting at the magic barrier indiscriminately because there were no targets to pick on.
