Fairly sure the only time I touched this spell was for meme Sunking for all of SL.
maybe try the original?
Heals a friendly target for (360% of Spell power) and automatically applies one of your missing healing over time spells to the target. If all of them are present, Nourish critically heals.
(current is 223% Spell power by comparison)
Or another option, ditch this spell altogether and replace the talent with Living seed or Empowered Chrysalis.
i remember when it refreshed lifebloom on the target…that gave it some synergy, and opened up various types of playstyles…(i forget if that was a tier set bonus or a feature though tbh…iirc it was Cata or MoP druid though)
that might work again with the new lifebloom talent options, idk…but i agree, it’s just a dead option until it’s innovated somehow…we don’t need a mastery super heal, because regrowth can be powered up to be better in almost every regard.
