I sent a PM a while back offering to write you a macro to do specifically whatever it is you're trying to do. Never saw a response, so I'll assume you're not interested since you've responded in the thread since then.
the guy is new, so i dont think this is about so much hailing everymob in the zone as it is really just learning what he can do, hailing everymob would be a simple macro to start learning on, how ever silly it may be,
i know what he is wanting the mass hail shit for and its not a hail wam u get xp its a hail and mob spawns kill get xp hail again mob spawns same spot again kill xp ext ext ext i seen people doing this for a week straight.
if ya dont know what im talking about ask some of the people on ur server that was 85 before everyone else and they will tell you
