I posted in my Mastery thread with the macro text in the eq2 forums that you could not use the macro with fighter Mastery spells because they are a proc, not a spell cast on a mob type.
The macro works great for all of the mage/priest and scout classes but because of the way the fighter mastery is you cannot macro it.
The full macro is posted
here for any who might want to try it.
It is all explained in the post =)
