Resubscribe?

I played during the the lightning troll release a year ago or so.
Has a lot of new content come out since then?
I'm thinking of resubscribing just to beat all the current content in LFR, but do not know if enough stuff is out to keep me busy for a month?
Any suggestions or opinions are welcome.

There are plently of stuff its worth it ! and you should resub + you can ask for SOR (scroll of ressurection from a friend) and get a kewl back if you allrdy dont have it, the content in MOP is really huge there are also flex raids which are pretty easy but fun to do ;))

Wait for WoD
