I have been thinking, when we are fighting Garrosh at the end of the raid, how do us alone, being Alliance and Horde even together, stand chance against an Old God powered Garrosh? From what I have been reading, near the end of the encounter he absorbs all of Y'Shaarj's power(Correct me if I'm wrong), so how are we powerful enough to defeat him? It took an army of Titans to kill Y'Shaarj so how can just a small group of mortal soldiers kill it again? Is it just a fraction of his power?
