Because he won't jump up or down a cliff when it is important, like when I am being chased by a boar or a badger. What is the knack for using cliffs? Is there some kind of height thing happening that I just can't see?
The other problem, assuming I safely climbed the cliff, is he misses with bow, like stupid misses. Everyone says 10 marksmanship and 10q bow, but I can't seem to hit anything. I made two close one shot kills, a fox and a deer, and since then always miss.
