Should I Get Mists of Pandaria?

[TheGateKeeper]

Old time WoW player here; used to play vanilla and outlands. Thinking of going back to the game but need some opinions first.

What's it like guys? I did see some videos and it does look pretty, but looks does not equal fun.

Was thinking of restarting the game using a Panda monk to see what the new class feels like.

Also, do I get the previous expansions if I buy MoP?
