Well, this is sorta who i am from the WoW point of view.
I have been playing the game for 3 years, and had a great deal of knowledge on the game as it was before cataclysm. I now am leveling a bunch of new toons of classes i haven't played before. Right now, i play a lvl 85 dk called Supadeath and a Warlock called Jaamon. Other classes i have played before cata were: rogue, hunter/tard (back in BC lulz), and druid.
