Seems silly but...

Are you mousing over someone when you push what ever hotkey the macro is attached too? Like not yourself but even someone just standing next to you.

Mine looks like this for Physick:

/micon Physick
/ac Physick <mo>
/ac Physick <tt>
/ac Physick <me>


I don't think parenthesis effects it, my friend just said his macros are in parenthesis.
