I highly disagree with the last. If a Hobgoblin walks up to me and clobbers me for 25 points damage using what looks like a mundane longsword, I think I-as-player (in or out of character, either way) have a right to ask "How the hell did it do that?" and expect to get some narration back that points to the cause e.g. "Even his muscles have muscles" or "She looks to have gone berserk" or something that I can use to inform my next move, assuming the 25 I just took didn't drop me.Why is that a problem? The player has no idea how much damage a monster can do and no idea how that damage is calculated.
The only person with a problem is the sausage maker - the DM.
How did the monster do X damage is not a question that any dm should have to answer.
Put another way: a player might not know how much damage a monster can do but should in theory know (or, from experience, be able to learn) what damage a longsword can do, and a longsword is a longsword no matter who or what happens to be wielding it at the time.
