Battlefield 3 Premium & Close Quarters

Not that I'm gonna buy it but I'm curious about your feelings about CQ and Premium thing.
Does CQ include interesting maps where attack is not only understood by standing in one place and waiting someone go out of the stairs? Like it is mostly in Metro when team does not want to take the risk and attack...
And does Premium is worth spending so much money? Do you think it's fail or must-have? And why?
Tho I ask such questions Imo spending twice more than game cost me on some freaking 20 maps is madness.
