Light stepper is useful for Honor mode unless you want to take on "worlgaff" or whatever that thief is whenever you think there might be traps or actually use him as your main scout.
Even if you got a solid combat plan, nothing makes short work of your party like one mine in a bad environment and then it's back to the drawing board again.
I just made my main leader have some perception points and light stepper. Very handy when doing the orc stuff around level 6.
