I have been playing since beta but didn't do much until TBC, had my Warrior Smalltanker grinding through normal and heroics to get gear to tank Karazhan. The whole rotation thing was much harder back then with CC required in raid content and heroics. TBC lasted long enough for me to get to 70 a warrior, priest, Shaman (for SSC) and then my paladin tank. The mechanics changed dramatically in there. It went from being a pain to get through Kara to solo-tanking it with little to no CC by the end of TBC with the Paladin tank.

Wrath was fun and I did some limited boxing.

Cata is challenging but doesn't feel epic. I am sitting 9 levels away from max on my Shaman team and have tried a mixed PVE/PVP team unsuccessfully.

I wasn't too impressed with basic-WOW but loved TBC. Wrath had such a great line and beautiful zones. Cata, well it has the water zone.
