I have stuff like....
/action "Sacrifice II" <st> : So I can cure anyone with this macro.

I also have...
/action "Roaming Soul" <me>
/action "Shock Spikes II" <st>
because I always use Roaming soul with SS when I buff my party.

If you have some set of spells that you always cast together, you might want to make 1 macro for it, for example Pro, Shell, SS, and Stoneskin. I would make sure I use syntax <st> for sub-target because that will make cursor pop up and let you choose for yourself when to execute the spell, just so your character and auto macro won't skip any spell (in case the casting of previous spell is not done, the nest one may get skipped when you try to cast.)

I even use /recast "Stoneskin II" before my Stoneskin macro so when, if, I try to use it before cooldown is done, I can see how long I have to wait.
