It would be even more efficient to use something like CTRL+MOUSEWHEEL to control our stance. This way we could have a fluid change of stance even more precise than the steps.
2nd Ranger suggested a possibly even better control scheme: Using a modifier button + moving the mouse could be even more precise and could be used in different directions. An analog stance!
The stances steps usually fall too high or too low. Using something like the mouse movement or wheel would enable very precise stances, limiting our body exposure even more.
I sadly couldn't find a video or image to illustrate our thoughts. I hope i explained them well enough.
