I only play pures. My Nord warrior doesn't use any potions, wear/enchant any gear, use any magic (except shouts as I was role-playing as the Dovahkiin), or use any other sorts of ranged attacks. I may use a bow if I was hunting docile animals, but I don't hunt so I don't usually use it.

My pure mage will only use the 5 main schools of Magic, maybe I will try enchanting after I've mastered the 5 trees. I've only made a pure Destruction, not the all-skilled mage.

My Archer was pure too, Light Armour, Archery and Sneak is all I put perks in. But I got a bit bored so I added a single dagger for stealth kills/assassinations for a change.

I'm thinking of making an Imperial Paladin, Heavy Armour, One-handed (Mace), Block, and Restoration (for role-play). I may add Smithing and Enchanting as I haven't tried these but I don't want to ruin the game.
