No prior dialogue, no buildup, not even the whole part with her robot. Feels like more than half the instance is just gone. Even Prae removed cool stuff like the cinematics with the robot. There's not even an option to run the original version. A lot of people would have been happy if they had just made the cutscenes skippable. The overall atmosphere of both instances has been nuked.
Complete removal of content with no way to revisit is never a good thing. Even the dumpster fire known as acti-blizz learned this lesson after cataclysm.
Edit: In my honest opinion, I feel like the biggest improvement is the boss fights themselves. The new mechanics were solid.
