One of the awesome things about skills now is that they can be modified by whatever ability score is more appropriate to the situation. That being the case, why do we need both Search and Spot as skills? I get that there's probably some subtle, pedantic little difference, but isn't the main difference just that one uses INT and the other WIS? What really separates a WIS check using Search from a WIS check using Spot or an INT check using Search from an INT check using Spot? I'm just not seeing the point in having both skills anymore.
