Wow! I'm surprised at the number of responses. Thanks everyone.
I guess the tactile sense is different from game to game. I could see it either way.
If the limb takes structural damage, does it hurt until repaired?
Would the repair cause pain or act as healing? Sometimes I make healing itch or a brief pain at best.
Maybe having a temporary animation is best if you go with the tactile sense route. Or you could have touch sense but not pain, heat or cold.
I guess the attack chart would be case by case; club attack, mace or above Strike I, however it was designed. (War Mattock!)
It would be intriguing to have different attachments with individual uses.
