You probably have /wait set too low.
Try setting up the macro as such:
Code:
/micon "Foresight"
/ac "Foresight"
/ac "Featherfoot"
Tap the button twice to get both to activate
Or try
Code:
/micon "Foresight"
/ac "Foresight" <wait.2>
/ac "Featherfoot"
Since they added the new <wait> syntax I stopped using /wait all together. Gives more space and looks cleaner. On top of that with the way the battle system is paced, using any wait is discouraged as it wastes minor amounts of time. During that macro you have a chance to lose hate to a rambunctious DPS whereas you have more control of other skills with the first macro I presented
