Everything has changed. Its not even remotely anything like what you played in vanilla/TBC/wrath. As the above poster said, they could literally sell it under a different name. Sad really, WoW used to be such a masterpiece of intrigue and adventure, and such an amazing value. Now, you couldn't pay me to play it. To its credit, it is better from a technical aspect, as in, it looks and runs better, and I imagine less bugs etc. But as far as game design / game play goes, its a sad, sad mess.
