While waiting, we may not be doing nothing. Just not all of the things we enjoy. Lately for me, the waiting game has mostly included doing dailies and making as much money as I can. I prefer to raid. My work schedule does not really allow it right now. There are the weekends, but that is time with my fiancee.
I am waiting for next patch. Then I can run Heroics like there is no tommorow. Ever since pre BC, 5 man instance have been my favorite. You can grab 4 of your favorite fellow players and bullshit your way to glory.
What are you waiting for? Is it next patch? Arthas?
