Just got home here is my druid healing macro:

/castsequence [target=Rou,nochanneling] reset=combat Rejuvenation,,,,,Lifebloom,,,,,,Lifebloom,,,,,,,Li febloom,,,,,,,Rejuvenation

I seem to be way over healing to the point in each trash fight I have used 1/4 of my mana. So I have to drink after each pull, which seems like overkill to me.

The commas act as a click correct. So if I'm clicking my button every second - it's tied to my paladin's tanking macro - it gets mashed a lot.

I also have wild growth on another button, with my DPS group (mage, hunter, priest) so that it gets triggered every time the cool down is up.
