Well, as a side note, I'm currently coming with my own extensive rules "re-write" and I reclassified several different attributes. I felt Wisdom was the stat that seemed odd (the ability to be introspective yet also covers being attuned to fine details of the outside world) and also felt Dexterity was a bit overstacked mechanics wise. My solution was a bit more radical however (and most likely not popular, but since you are asking for ideas I'll post it).
I combined perception, and the ability work with complex puzzles and such into one stat that replaced Intelligence. I then combined the introspection of willpower and "book learning" into "Wisdom". Dexterity was still used for gross motor and fine motor skills. However missile accuracy fell under the stat which replaced intelligence while all of the missile weapon feats still required a minimum Dexterity to use. For anyone that fires missile weapons, yes it absolutely takes steady aim but it also takes a quick thinking mind - adjusting for angle, wind speed, identifying the proper target and thinking "one step ahead" if they are on the move, and so forth. It takes, IMO, a quick minded and dexy character to figure out friend from foe in the split second that they need to and take the shot.
No playtesting done as of yet, but just a out of the box suggestion.
