Blizzard has the last major patch for Mist on the PTR (Public Test Realms) and I decided to take a look around and the changes are amazing. I have embedded 2 videos to this post. The first is how the Vale of Eternal Blossoms (Major zone for both factions) looks today and the second video is how it will look with the next expansion. Let me know what you think.
I would recomend watching both videos at the same time. You can see just how different the zone will be.
