or... you can match things up with your pally.

everytime your pally judges, cast holy fire.
everytime your pally consecrates, cast mindblast.
smite in between.


to answer some questions.
reset=6 will reset the macro 6 seconds after the last succesful spell.
reset=combat may not work since you'll be in combat quite often.

my questions:
currently what is the cooldown for your holy fire and mindblast? i know its different with talents. also, what is your casting time for the three spells?
