Do you react similarly to combat?
After all, the DM is telling you that you have lost HP. You have lost conciousness. Hell, you might even be dead, with zero input from you. Do you have a similar level of "I don't think Mr. B would really do that?"
The point of the exploration of character is that the mechanics give you a new avenue to explore that wasn't there before. Do you similarly react so strongly to Sanity rules? Or Piety scores? Both of those are mechanics that tell you what your character thinks. What's the cutoff here
@Oofta? Any and all mechanics related to how your character acts? So, we're not allowed to have any alignment rules, no traits or flaws?
You keep making very strong statements but, I don't think you've really thought about the implications of just how many mechanical influences there are in what your character thinks.
