/cast [help,stance:2,target=targettarget]Intervene;[help,stance:2]Intervene; [help,nostance:2]Defensive Stance; [combat,harm,nostance:3]Berserker Stance;[nocombat,nostance:1]Battle Stance;[combat,harm,stance:3]Intercept;[nocombat,stance:1]Charge


look at this macro, it works, but also i need to charge while in combat because when i use it i cant charge again because im in combat ,i can only intercept again after using my macro ...can anybody tell me how can i edit this macro??
(remember that i can charge while in combat bcause i am arms spec)
