I am a marksman who relies on short bow now. I also have a range passive
IN addition to everything said already, I find my shortbow to be much more reliable. It appears to be evaded 30-50% less than my long bow. I swap out bows depending on the fight. Longbow to soften the target and not take his, run in with the shortbow, get the target lower in health, then hit SOTW and finish the job.
Shortbows also hit harder.
