I don't use a lot of healing macros for the same reason as everyone else, queuing up abilities.

But my most used macros on the PC are my summons, so I can hotbar their individual abilities (primarily Embrace). Same with my SMN. Not at my PC, so syntax might be off:

/macroicon "Summon"
/ac "Summon"
/hotbar pet "Embrace" Eos (hotbar#) (slot#)
/hotbar pet "Whispering Wind" (#) (#)
etc...

and

/macroicon "Summon II"
/ac "Summon II"
/hotbar pet "Embrace" Selene (hotbar#) (slot#)
etc...

You need to specify Selene on the Embrace line, or it will default to Eos's Embrace. If I need a cure bomb, I can hotbar Embrace next to Physick/Adlo and just space 1,2,1,2,1,2 for example. I hotbar Whispering Wind next to Succor for the same reason.
