@clearstream, I will try and state
@FrogReaver's concern, as I understand it:
During combat, participants make decisions for the characters they are controlling which
matter to how things turn out (eg decisions to move, to cast healing spells, etc) and which are chosen based on
knowledge of the mechanical state of the game (eg where another character is on the grid; what a character's current hit point total is; etc). But at least some of the
fiction that corresponds to those mechanical states
can't be known until
after the decisions that matter have been taken and the actions resolved. Because only after the event do you get the sort of "emergent" fictions that you are putting forward.
This means that
those decisions, and the knowledge they are based on, don't themselves correspond to decisions being made, and knowledge possessed, by the character whose action is being chosen by the participant.
In that particular sense, D&D combat is fictionless - ie it involves purely mechanically-driven decision-making that (from FrogReaver's point of view) "masquerades" as in-character/in-fiction decision-making.
