Would it help if they changed our Mastery to the effect of Ascendance and give Ascendance the effect of our current Mastery, with an fixed amount, lets say 60%.
So that would make:
5.2% of base mana
Instant -3 min cooldown
Requires level 87
The Shaman surrenders his physical form to the power of the elements,
gaining the ability to transform into a being of raw elemental energy for 15 sec.
Increases the potency of your healing spells by up to 60%,
based on the current health level of your target (lower health targets are healed for more).
Then they can balance the healing spells better.
Mastery: Tranquil Healing
Distributed 12% of all single target heals done evenly among nearby allies.
Each point of Mastery increases Tranquil Healing by 2%.
