As someone who has played a huge variety of MMOs over the past 15 years, I will give you an honest answer.

Don't force yourself to keep playing a game. Don't search for an excuse to continue like you are doing here. You need to be able to ask yourself "Have I done enough here?" and "Am I ready to take a break from this game?"

This is a very nice game as far as MMOs go, and I would hope you enjoyed your time here. But don't be mad at the game if YOU have managed to burn up all / most of the activities avialable.

Also, if you are familiar enough with WOW that you can make the claim that "WOW does this better" or "WOW has more of X", then WOW is probably not the game you want to go play right now. Because you have already been there and done that.

If you are looking for something fresh and new to spend your time with, maybe look into one of those other MMOs coming out soon like Eldar Scrolls or Wildstar.
