I'm leveling a resto shaman alt for casual play, using healbot. I am curious - how do others using healbot assign their spells to the buttons? For example, on my disc priest alt, I have left click as flash heal as that's my emergency heal and right click to penance, as I use that pretty much on CD. Then with shift+, I assign my next two commonly used spells, ctrl+ and alt+ get the slightly less commonly used ones. I confess I don't even bother to bind the spell "heal", as I'd prefer to use atonement or some better direct heal.
With my resto shaman being only level 45, it's not a pressing issue as I don't have a lot of healing spells. At the moment, it's:
Left: Healing surge
Shift left: Earthen shield
Shift right: Chain heal
Ctrl and alt ... TBD
Like with my disc priest's heal spell, I am having trouble justifying the use of healing wave. They both take so long to heal so little. At level 45 with full heirlooms, I am spoilt for mana though.
