Right, so that's all I'm really saying here. There's a type of gameplay that 5e players don't find fun, and so 5e skips over that part. You can go around searching for traps with a 10 foot poll, relying on GM adjudication over skill rolls, but contemporary players tend to not like that and thus skip over that part. It's not what makes 5e, "5e."Old school style of 10 foot polls or sending a flock of chickens ahead to trigger any traps, or worrying about ear seekers if listening at a door, is less fun for most players. So 5e intentionally skips over that part.
