Here's a question then. You say you are a Hunter class, correct? Are you trying to use a bow to kill people? Because if you are, you really REALLY shouldn't bother. The only hunter bow skill I have ever found to be of use in PK was Aimed Shot Torso. Once mastered it has a 'fairly high' chance of succeeding in knocking them back, which lags them a bit. Other than that, use another weapon, any other weapon. Well, I should say the last Hunter I played faired well enough at staying alive when using aimed shot torso.
