What do you all think about this instead of the healing wave only...
for the resto shamans keys

/castsequence reset=combat Healing Wave,Lesser Healing Wave,

With mysetup my resto shaman can only get 12 to 15 healing spam

but this can get me 15 to 20, heals casted, my lesser heals between 4 and 6K while the healing wave heals between 5 and 9K on my tests, but then again my gears are not geared well at all.
