Hmmm on my mixed group (lock, 2priests, mage, pally) I did not use any fancy macros, just /follow and /target. I guess it's my playstyle but I always hated setting up any type of macro. All I did was bind similiar casting time spells to the same keys. Then I clicked the keys on my tank, it had no binds. Since mages/locks/priests have very similiar spell casting times it was pretty easy.
