Gratz on 70 !
And Kara is not the end game hehe. There's Gruul's, Mags, SSC, TK, MT, BT and Sunwell. But you have access to the sweetest gear the game has to offer now and you will enjoy getting it because I know I did.
I remember seeing
Despair drop and was practically screaming "UP !!!!" over Vent.
Gratz again on 70 and welcome to World of Warcraft :P
