Ultimate Evil - Illusionist, Necromancer (pretty much how I usually build a Vampire)
Duel-casting a Frenzy spell into a group of bandits and watch them tear each other to pieces, only for the last one standing to have to fight his friends all over again after I've raised them with my dark magic. *cue evil laugh*
Good - Paladin
Sword, Shield, Heavy Armour, Crossbow and Restoration spells. If you learn how to utilise the playstyle, you become pretty much unstoppable. Heavy Armour and a Shield provide the best protection, coupled with healing magic, wards, etc - almost unkillable.
Immersion - Ranger
Hunting in the wilds without a care in the world, trying to keep out of trouble from those tiresome bandits, or taking the fight to them in the name of the Jarl. Earn an honest living collecting meats and pelts from the wilds, camping under the stars and selling your goods in the cities to pay for a couple of nights at the inn with friendly faces.
