I don't see the issue with Setsuna's effect. There's nothing sacred about your stats and skills; once you start fighting, anyone that looks will more than likely be able to figure them out with some guesswork. Using an effect the system provides to figure out a majority of your opponent's arsenal isn't metagaming; it's the natural instinct to figure out what they're doing and/or what you're going up against. Demoting it to a 'Scan' skill, in my opinion, is unnecessary.
