Garrosh is a tyrant that has lost control of his lust for power. He is so proud of his people and his race that he is determined to embrace corruption, greed, and power to create it. However, it took an exploration of Pandaria to teach the Alliance and the Horde the knowledge, courage, and strength required to see this. They are so aware of this, that they are willing to band together despite past conflicts to do what needs to be done: Prevent a world where Garrosh's corrupt rule is supreme.
The American government (maybe even all governments, this is up for debate and Socratic Method) is a body that lost control of their need to police the world. They are so proud of their technological prowess and their brand of freedom that they are determined to promote military campaigns throughout the world to maintain it. However, it took the internet uniting the world together to teach the average person the knowledge, courage, and strength required to see this. We are so aware of this, yet we are not willing to band together as a united world to tell America and all governments that war is no longer needed. It is only wanted.
What do you think 5.4 or even the expansion has taught us about the world today? What can we do to take the lessons we learned the past year back to the real world where it is really needed? Are we ready to say together as one world body: We no longer need war?
