I am having a hardtime having fun with the lock in cata. I was a mage for a long time before switching to lock, I felt mage had got boring at the time and decided to take up my warlock, loved the class, love the mechanics back then but now I don't find it fun at all especially at 85. To me the class has become "watching the ISF buff" more than anything else. The class has gone from fun to tedious from my point of view, i'm utterly disappointed.
