I have a pally and a druid. I have the same macro keyed to the button I currently use on the pally windows for HoR.

This the pre-patch druid heal macro i used:

/tar Pally
/castsequence reset=combat Wild Growth, Lifebloom, Regrowth, Lifebloom, Healing Touch, Lifebloom, Healing Touch, Rejuvenation, Nourish, Regrowth, Swiftmend, Lifebloom


Current using on the PTR:

/castsequence reset=combat Wild Growth, Regrowth, Healing Touch, Healing Touch, Rejuvenation, Nourish, Regrowth, Swiftmend
