so why u just dont use the aptitude dance and song function of the walker ?
-Aptitude Dance and Song (if party leader has a check on this, it will auto kick the bd and sws when they sing and dance (if auto invite is on will also reinvite them right after they sing and dance, This is so the bd and sws don't get any of each others buffs)
better then messing with scripts
or just create 2 macros in l2 : 1. /invite bladedancer 2./dismiss bladedancer - if u wanna buf just press the 1st one the bd will automaticly dance and after that press the second button and u will dismiss it ...
