See my point? Why do we not add DEX to hitpoints? If HP is that abstract, why the hell not?
If they suddenly changed the rules to include this... I'd be absolutely fine with it.
Here's the thing... many of us believe that the game and the story are really two separate things. We need game mechanics because we're playing a game. We're rolling dice, we have game rules, we have conflict and resolution using said rules and dice. In addition to that... we have a cooperative fantasy story that the players at the table are writing together.
In truth, we don't NEED game mechanics to tell our story. Anyone who's done long-form improvisation or something like Fiasco can tell you that. The story can get written by all the participants whether or not we include dice rolls or not. As a result... if we do decide to add dice rolls as a mechanism for deciding as a group the resolution of certain conflicts... all that matters is that it adds to the FUN of writing the story. It doesn't matter what those dice rolls are, doesn't matter what those dice rolls represent... all that matters is that the dice rolling becomes a FUN addition to what we are doing.
As a result, so long as the mechanics are fun-- which usually means at least partially related to the conflicts and resolutions, as well as beating odds both long and short... the specificity of what those dice rolls represent do no matter all that much. The story is the story and we will create it together-- we don't need the game mechanics and the dice to create it for us. Which is what being beholden to such meticulous, consequential, and nitpicky detailing of what die means what effect and does that accurately represent reality yadda yadda yadda... we're trying to get away from or not worry about.
We care about the macro story result of the monster dying... not the micro story of which attack did which hit causing which wound resulting in which bleed concluding with which form of unconsciousness, etc. The story is the story... not the individual play-by-play of the dice game.
