Maybe you want to give berserker/mage a try?
I have played two berserker/mages already (one good, one evil), their "enrage" ability make them good Kangaxx killers. Because I have exp cap remover installed, I usually dual class them at around level 12~15, it takes longer to gain back your abilities, that's the down side.....but I prefer extra proficiency slots and HPs. But you can also gain HPs from your familiar....
A pretty good combo would be dual wielding Crom Faeyr and either Daystar or Celestial Fury, depending you like long swords or katana better. Anyways, happy dualing.
