My main will be (and always has been) a protection Paladin.
As for my favourite class NPC, I would have to say Tirion Fordring. He is one of the iconic paladins of the Warcraft story, but what made up my mind was the showdown between the Lich King and Fordring & the paladins at Light's Hope Chapel. The words "your master knows what lies beneath this chapel" already made me think of the possibility of a artifact of Light underneath Light's Hope, and the Paladin class order hall being situated there fulfills that particular story for me.
