SPOILERS IF YOU DONT KNOW WHAT HAPPENS AT THE END OF THE KILJAEDEN FIGHT
Most people are probably focused on what its like to see Argus hanging in the sky while on Azeroth. But I started thinking about this from the Argus perspective. Right now, you can see Azeroth hanging in the sky from any point on Argus. Some of you may say "So what??" But don't forget, We've NEVER seen the other side of Azeroth. We've only seen one side. What if we go to Argus in 7.3, end the Legion threat in some raid, and while we do this Azeroth slowly turns in the sky. At the end, it rotates around and we see what's on the other side at last....and we see some GIGANTIC old god sucking the life out of Azeroth.
