I’m not sure why providing advice based on providing internal logic in a fantasy world along with a rational, is any less appropriate than advising someone to rearrange their stats for tactical/strategic reasons…..but whatever, dude…enjoy your game!
Because it is your internal logic, not the internal logic of the game system, or of many experienced DMs. Although well intentioned, your advice is too specific for a given DMing style, a style that most games do not use.
