Since shining aspects isnt really a good thing compared to the other 2 options , and its almost impossible to heal the amount of health that could be negated by Hardening Persistence, let me came up with an idea for it to make that trait viable.
Its in the row of improvement-traits for the Aspects actives (mainly improvements for you and allies) and doesnt scale very well with healing power. (Maybe 100more health per 1500Healpower)
So why not make it an AoE heal, that hits up to 5 people (you & 4 allies) ? Its not an strong healing, but it would make it in some situations an better choice than Hardening Persistence + Its not giving any improvements to the power-herald meta, since so many people are complaining about buffs to it.
So what are your thoughts?
