LOL. She probably hates them because they've been insanely overpowered for a while now, but I've noticed they're getting nerfed slowwwly.
I have a paladin, but my favorite classes are mage and rogue. It's possible have another class of the same type (with the exception of the death knight, I think). I think he just wants you to level him a paladin.
FYI, It was the hugest time sink of my life. I've been free of WoW for over a month now. :b
