I have noticed that when you are stunned in PvP, you can't move but you CAn still attack and use skills. Whemy bow bear gets beckoned by a melée warrior this means I can pop iron blood, evasion, and stomp and wind up with damage mitigation and a melée sitting stunned outside of his attack range, while I spam my attack button and pummel him with arrows. I have killed more than a few while I should be stunned and unable to do anything...
