I'm thinking of decoupling some of the aspects of wisdom and forming them into a new awareness or perception stat. Namely the stuff that relates to sight/sound/touch
I've never been comfortable with what I've seen as a bloated ability score (in terms of usage), I mean wisdom drives spell casting for divine casters, act as your will power (for related saves), helps you detects lies, and somehow allows you to more easily see the guy hiding in the shadows.
I've seen alot of examples that sort of fly in the face of this logic such as: the bodyguard that isn't exactly giving sagely advice but keen eyed; or how Gandalf, legendary for his wisdom, was not perceptive enough to notice Pippin messing with the well in Moria.
I know by the D&D description wisdom fits the bill, but traditional definitions of wisdom don't imply that people have better awareness of their surroundings (I checked both Wikipedia and the Merriam-Webster dictionary)
I'd likely couple things like search, spot, listen, track and read lips into the new stat while leaving stuff like sense motive and scrutiny with wisdom.
Let me know what you guys think, any feedback at all is helpful! Thanks!
