The rules for Movement and Activities While Traveling work hand in glove with the rules for determining surprise.
They don't, not specifically. Surprise is individual. Travelling mentions specifically mention the group (
they don't contribute to the group's chance of noticing hidden threats). Moreover, they don't match the stealth rule either. These are general rules to manage the party over a long period of time in an exploration mode. At best, it's an edge case.
The rules don't say anything one way or another about adventurers being "idiots."
No, but your interpretation of the rules make them sound like idiots. Again, in your experience, in a dungeon, do adventurers walk down the corridor not paying attention ?
And if they are, are you even properly using the surprise rules ? Because if you do, even if the ranger notices the threat, all others are surprised, which is stupid for them.
They just say that if you're doing anything like the listed tasks, you're not watching out for danger and you don't get to apply your passive Perception.
Once more, read the rules, they don't say that. They say that if you're not paying attention, then you can do other tasks, which is completely different.
Once, do you say that because an adventurer is taling some notes for mapping, he gets no perception checks and is mandatorily surprised ?
When combined with the rules for surprise in context, that means you're surprised if a monster tries to surprise you.
You are, once more, not reading the surprise rules properly. It's not a question of wanting to surprise someone in particular, it's just seeing, on an individual basis, whether you are more perceptive than specific members of an opposing group.
When you're surprised, you can't act during the first round except for reactions after your turn has passed. That's it. Any editorializing about someone making a meaningful choice to risk surprise in order to undertake a useful task being an "idiot" is all you.
Considering that most 5e fights are over in 3-5 rounds, missing one is pretty significant, especially if a monster gets to act twice before you do. Once more, in your groups, do adventurers take risks like mapping and risk surprise. Yes or no ?
The way you appear to run things makes Perception way stronger than may be intended.
And once more, I've shown you that, contrary to you, I'm running things as intended. You are the one who has zero knowledge about the intentions there, as demonstrated many times so far.
Hence the need to control "dubious uses," by way of requiring the investment in Perception to "fit the character's profile," whatever that means. That you also have most or all monsters try to surprise the PCs only makes Perception that much more critical in your games.
Because my monstres are not idiots either, of course, they will try to surprise any adversary. Doing otherwise would be simply stupid.
Contrast with how I do things: I don't care if the player invests in Perception and don't care if they have a passive Perception that is off the charts. Because I know that investment isn't free in terms of character creation and advancement, benefits every member of the party
No, it does not, unless you are, as usual, not reading your rules but the way you would like them to sound. But they don't again as demonstrated constantly over our exchanges. Read the rules. Listen to the podcast. Then, maybe, you can talk about the actual rules and their intent.
In particular, having just one member to prevent surprise is not enough. Just read the surprise rules.
, and because it will also come with the trade-offs and risks the rules establish which are sufficient in my experience to keep Perception more in line with other good choices. And only about 30% of monsters on average will try to surprise the characters
Meaningless statistic based on you mistaking the training in stealth with what the monsters would do. Once more, do only characters trained in stealth ever try to be stealthy in your games ? Sheeesh...
, so the players understand over time that they can risk having characters engage in tasks other than keeping watch for danger.
Only if they, like you, don't read the rules about surprise and stealth. And if you muzzle them in telling them: "because you took a few notes for a map in the previous room, you are considered blind, deaf and stupid until I tell you so."
