right now i use a mix of both click/repeater.regions and macros with most of my macros based around

/cast [target=targettarget,nochanneling] Greater Heal
you can also use

/cast [@tank] Greater Heal

/cast [target=player1] Greater Heal (modifying the # as required)


I realy like these two addons because they give a nice color visual of who needs attention

this is pretty much grid, healbot, and clique all in one addon. there is some nice youtube guides made by the author to help you customize it.

What I'd like to hear from the community is for a healer what is the ideal placement of the frames other than the bottom center.
