I love Dungeon World and I'm happy to answer questions about it, but there have been a lot of questions asked recently by a new user which all amount to the same problem of differentiating the rules from the fiction. (Does a shield protect the PC, even if it's not hit?, Should I tell the players the exact stats of monsters they fight?, Are HP part of the fiction, or part of the meta?)
I can't help but feel like these questions are mostly theoretical rather than practical problems and will attract very similar if not the same answers to only superficially different questions.
How should this be handled, does it even need handling at all?
