The initial post by
@GrahamWills didn't talk about a bad rule:
I interpreted, and still interpret, this as being a remark about
the result of a rule on a particular occasion of application being wonky fiction on that occasion. That is consistent with the rule being, in general, a workable or even good rule on most occasions (and hence not a rule that anyone wants to change).
As I may have mentioned already upthread, our Rolemaster play experienced this from time to time with initiative: the hard break of rounds, with its implications for movement, allocations of attack-and-defence, etc could sometimes produce fiction that made no sense given that the end of a round isn't a thing that occurs in the fiction. But if that happens once in 50 transitions from round to round, and the other times your initiative rules are either harmless or actively supporting sensible fiction, then you (or at least we) just put up with it.
