Perhaps the OP can now be un-banned.
To answer the OP's Q:
No, I don't think it was a bad idea to do an Asian expansion. I did not like MOP, and I did not like the way Asian theme was done, but it was more about lazy and low quality implementation on Blizzard's part. Asian theme could have been awesome if it did not overshadow Warcraft itself and if it were done right.
