Hm? But the objection is just because the skills either do or not do certain things--and Instinct is one of those where it's clear what it does and so's Clairvoyance, since they both come from F/SN in the first place. And whilst Instinct is great for fighting in conditions where you can't see what's happening or reacting to something that you have no way to detect, neither achieves an effect that would be "see clearly something you can't see". ^^;
