Ooh, I'm really surprised with the answers so far here, cuz for me I just finished up the business no matter what they say.

(I guess this is my sadistic side.. lol)
Hey if they want to get up, and fight me so that i can just overpower them them some more that's their choice. More weapon skill for me. at this point in the game its usually the bandits that are stupid. I'm wearing this armor that makes me practically immune to their attacks, and they just keep laying into me till they are panting and tired. I sometimes go walking around the dungeon looking through their crap and examining the environment while they pound into me uselessly with their inferior weapons.
it takes me a while to get to the point to where i can shrug off their attacks like as if it was nothing, and I enjoy watching those bandits trying so damn hard to hurt me.
I honestly wish they would have implemented a run away scared if it takes too long and the attack seems to not be doing anything. like: I cannot best you! I yield! and proceeds to run off. that way the player cannot exploit an easy way to get up to 100 Heavy armor really quickly.
