I have my hero as a mage/archer with the DK as a tank. I find this works well since she can conserve potions by switching to the bow while mana regens. In the hard fights, she uses mostly magic and potions to replenish mana. Both chars have 1 level of individual healing which saves some healing potions...The DK is 1H slashing melee specialist.
Oh, my DK can convert arrows (explosive) and the mage has a level or two in explosive arrow skill too....
