my physick mouseover macro:

/macroicon "Physick"
/pac "Embrace" <f>
/pac "Embrace" <mo>
/autofacetarget off
/ac "Physick" <mo>
/autofacetarget on


This toggles my autoface off, so I don't turn to heal.
then forces the fairy to cast embrace on the focus target if I have one (so I can set an override target for her), otherwise she heals my mouseover target too.
I also heal my mouseover target, and turn the autoface back on, in case I use dps skills next.
