I'd be accepting of them, but ONLY for headshots. Oblivion was already incredibly skewed towards player skill instead of character stats, I don't want that to grow too much more. I'd personally rather see some more driven-by-character stats return (I doubt in full out hit/miss, but in events where, based on your skill level, you will do either a lot more damage or very little damage every once and a while instead of normal damage).
I think adding a hit box system would add to the feel.
Certain parts of body
head
Chest
Abdomen
Limbs
Like if they made it 50 blade skill to accurately hit someone in the abdomen the right way aka stabbing through the lower intestines and thrusting upwards into the ribcage. Things like that would be dice roll accuracy and hit damage and will have different ratios for certain bodie parts.
Torso would be easy to roll accurately but not as much of a damage hit.
Limbs would be hard to hit but when hit they would lose a decent bit of health.
Head would be difficult to hit but when hit you do triple-double damage and a roll to see if you do critical
