The "skill challenge" as presented assumes a few odd things, such as that using one's perception where there are no bandits somehow tells you something other than that you see no bandits at your current location. Why is it less silly to make a Perception check before picking a route than it is to bound along like a giant grasshopper? IMHO, they apply equally as presented -- which is to say, not at all.
I think we're laboring under an example of a skill challenge that isn't particularly good. Of course PCs are going to use perception to foil a potential bandit ambush. That's how the rules in general are applied when the ambush actually starts! So it's not really appropriate to use in a skill challenge to figure out what road to use to avoid bandit attacks.
I think you are looking at this wrong. The Perception check made in the context of a skill challenge isn't a matter of what the character perceives right at that moment, but instead a measure of how perceptive the character is during the execution of the party's plan.
Why would a player even imagine that bounding would help? Because his reading of the skill challenge formula suggests that it would!
This is why I suggest not letting the players realize they are in a skill challenge. Players look for ways to use things to their best advantage and have their characters act in unnatural ways sometimes. Unless you're going to take control of their character you have to let them do stupid things and mock the silliness in-game.
Moreover, let us assume momentarily that the DM knows where the bandits are. Presumably, then, scrying on their location reveals the bandits, and scrying elsewhere does not. If you know where the bandits are, they should be relatively easy to avoid. Why bother with the "skill challenge"? If you know where they are not, that knowledge can help you pick your route, but why would the PCs not have to still pick their route? "If they're not at Dead Man's Valley, they're probably in the Singing Wood. We cut off the road there to the east, giving the Singing Wood a wide berth." Again, if the bandits are in the Singing Wood, why bother with the rest of the "skill challenge"? If they are not, how did the scrying actually help the PCs?
It was mentioned that there are different approaches to this. Plotting out exact movements of the bandits and then plotting out the exact route the PCs take would not require a skill challenge. That challenge is more tactical. The skill challenge instead presents a more abstract resolution. I prefer the abstract only because I do not wish to spend too much time detailing the land between Greyhawn City and Ruins.
This just smacks of the "quantum states" approach that 4e seems built around. The bandits are in/not in the area you pass through based on your skill checks.
Or it is abstract. How many 1E DMs with a random bandit encounter chart like the one in the module knew where the bandits were? You didn't even know how many there were and of what kind or whether they would even show up (1 in 6 chance). This was an abstraction back then and the skill challenge changes it into a different kind of abstraction now.
I have no problem with random encounter frequency being reduced through skill use....woodcraft, for example.....but the idea that a set encounter changes locations because the players decide to have their characters march down the King's Highway, and, hey, they made X successes before Y failures, sets my teeth on edge.
Well luckily the example was based on random encounters, not a set one.
Moreover, the supposed strength of the "skill challenge" system is that the players get to use the skills thier PCs are good at, rather than (as in all other skill-based systems) the ones that obviously apply.
No. That is not a strength of the system. The strength is in the framwork it provides the DM to fairly and consistently adjudicate non-combat encounters. It is not an exercise in trying to find a use for your key skill in every circumstance.
Frankly, I fail to see anything that "skill challenges" are an improvement on from complex skill checks in 3e.
I'm not familiar with 3E complex skill checks. But no one has been arguing skill challenge vs. complex skill checks, so why would you even bring it up?
