Sorry, my bad. I though that it should be used only for buff as in WW rotation, but I have realized after release of 1.0.4b, that tiger palm is used between gaps. Will be fixed in next version.
I would need some time to find this things by myself, then I can debug it and find solution to this problems. It would be better to know on which boss you had problem with "doing nothing" and what talent build you had at that time. And maybe to have the log of the fight from Honorbuddy/Logs/Your Character name/ directory.
Basically it uses chiExplosion rotation, if units are stacked near your current target by 8yrd+Hitboxradius of Target.
I found the reason why it uses tiger palm and it's single target rotation for chi explosion. So it's checks if have 4 chi, then using 1 TP to burn 1 chi and then using chi explosion with 3 chi. The reason is that not all targets were stacked by 8 yrd radius of current target, that's why it uses single target rotation here.
And I will look for improving the opener rotation(Preport and ChiWave will be used manually anyways, because bot doesnt know the DBM counter, that's why it must be used manually).
