Are you wanting to use a bow for the extra distance? Not sure why you are asking. You have hate and aggression skills. At the higher lvls a bow is a nice addition to group pvp though.
Hmm, not sure abou that. I have always been the puller using aggression, range is 600 I believe. I would hate to be the archer that aggros too many mobs and I cant get them all on me. I know my healer sure would be ******. Maybe someone else can help you that uses this tactic.
As a non archer your range with a bow would be 600. You already have skills that are 600 range and as Saab said 900 range with drain health. A bow isn't going to help you with pulls.
