The turtle island seems fairly complete and the quests are pretty good. The only exception is the ending where the Pandas interact with the Alliance and Horde on the island. That part needs a lot of work. I still don't know if they ever explained how the Horde got on the island.

"Crazy pills, you say? Hmm... no idea what you're talking about."

Gah!

Been taking some of my own medicine, it appears... :(

This should have been down there (/points down one post)

I expect that the Pandaren starting zone will continue to change. At this point in the Cata beta, the Worgen starting area felt just as "complete", but it is very different from what we have now, in terms of quest flow and objectives, and does have much more story to it.

@Puntable - Horde that are on the island were prisoners inside the Alliance ship that crashed. You get about one line of text to explain this. Overall, that entire section with the Horde/Alliance meeting business needs some serious work.
