When it comes to rules, what makes you say "I recognize that the council has made a decision, but given that it's a stupid-ass decision, I've elected to ignore it"?
In other words, what's an official rule or interaction between different rules in Pathfinder 2e that you think is dumb?
Creature types. Not just in reaction to the 2025 Monster Manual. I consider this a GM-facing rule, subject to by interpretation. So when a Paladin uses Divine Sense, or a Ranger uses a similar ability, or a Cleric uses Detect Evil and Good, etc., or a Ranger has a Favored Foe, or a Druid casts Speak with Animals, etc. - it's up to me whether a creature counts as a Beast, or Evil, or extraplanar, or whatever. I go by the flavor that the design is going for, and I allow creatures two fall into more than one bucket. A dragonborn might count for some things that only apply to dragons; a fairy dragon counts as a fey and a dragon; a beholder zombie might count as undead or aberration or both depending on what the feature is trying to accomplish; a Warforged might be humanoid and construct; etc.
