I played awhile back, albeit not to a very high level - I've gotten my wife to try the game out and she's pretty much a 'wade in a slaughter stuff with big steel' kind of girl... so I'm thinking Champion. She doesn't want anything that complicated, so hopefully that is the right choice for her. If its not, let me know.
Besides that, I'm trying to think of a class that will be the perfect match for her - so what would that be? A cleric of some sort? Or a ranged DPS? I would assume a melee DPS would need a healer more than anything but games are different, so let me know your thoughts.
