So much has happened in 2009 and there is no way I have time to cover it all. The best thing that has happened in wow is of course patch 3.3. Hands down the best patch in the 5 year history of wow.
Best new content, greatest talent and ability revamp, new looking for group cross realm tool, and epics for everyone who can't get into raid.
World of warcraft cataclysm is going to hold so much new content, story, raids, battle grounds, new races, etc...
I think I am going to level my way to 85 in dungeons mostly.
