Lesser Healing Wave is a shaman healing spell intended for fast healing when mana is not the primary concern. It is generally less mana efficient than Healing Wave, but has a much shorter casting time. The spell is commonly referred to as 'LHW'.
While Lesser Healing Wave has a short casting time, it does significantly less healing per second than Healing Wave does when talented to reduce the casting time. The spell is very useful when there is a high risk that the target will not survive long enough for a slower heal to land, but it is generally not well suited for healing a tank due to the poor healing per mana and healing per second.
Casting Speed:Nature's Swiftness can turn Lesser Healing Wave into an instant cast spell, though Lesser Healing Wave's speedy 1.5 cast time makes this unnecessary. This talent should be used with other, slower-casting spells.
Miscellaneous:Ancestral Healing causes the spell to increase the target's armor when it has a spell critical effect. Ancestral Awakening allows the spell to heal a secondary target for 30% of the amount healed every time the spell crits.
