I was perusing the old talent calculator for classic, when I came across this talent:
Healing Way: Your Healing wave spells have a 100% chance to increase the subsequent healing wave spells on that target by 6% for 15 sec. This effect will stack 3 times.
Sooo, my idea for a rework of restoration shaman would be thus:
Deep Healing: Your Healing Wave, Healing Surge and Chain Heal spells increase the subsequent affected spells on the target to heal for an additional XX for 15 sec… This effect will stack XX times.
The amount would obviously be affected by your mastery percentage.
as to wether only the specific spells buff subsequent specific spell, or affects all, would be up for debate. Ie: Casting a Chain heal two times puts a 20 percent buff to your next Healing wave, Healing Surge, Chain heal. Or, Casting chain Heal two times puts a 20 percent buff to your next chain heal only.
thoughts?
