If you are new, Hunter is the best choice... Exp is easy, you have a pet to aid you, skills are easy and you hit really hard compared to other classes. Paladin is overpowered in Wrath of the Lich king, but he is not noob friendly...and warrior...Better leave him, he is the most difficult class in the game ( you have to manage 3 different action bar and time your spells perfectly) )
