Two Simple Requests to make skyrim more realistic/interesting:
1. Knockout NPCs - The ability to knockout enemies with shield bashes, h2h and other non-lethal attacks and sneak attacks. This would render an NPC all ragdoll and "dead", but they would wake up after a day and may or may not be hostile to the player.
2. Permanent Yield - I would love it if when someone yielded to me (go down on one knee), I wouldn't have to finish them off because seconds later, they get up and start attacking again?
Instead, I think the NPC should either:
a ) Stay on their knee for a few minutes, then hobble away
b ) recover after a minute or so and run away
c ) bleed out and die a few minutes later.
Thoughts?

Followers wouldn't eternally get up from dying to fight your battles for you while you hide in a corner snickering (unless you heal them or cast a rally spell maybe?)
Boxers black out form anywhere from a few miliseconds to a minute or more(rare), anything longer is called a coma. Only batman does that sh*t
