I think the auto run should be controlled by mouse not just running straight forward, banging everything that's on the way.
I think most people will never use the autorun because it's not that helpful, press and hold W + Shift is actually making my fingers quite tired from long hours of play plus my keyboard is mechanical blue switches which required me to do more force to press and hold compare to other types mechanical or regular keyboards.
I think next update should make this autorun more efficient by adding mouse to control the directions while our character keep running.
