Ofc the issue with getting the other "grown up" healers deeper and more complex deepus gameplay, is then the "Complexity reward" associated with them. 3 out of 4 healers are complicated and thus logically and reasonably demand a potency reward, more work=more impact.
That leaves the 1 simple 1 button 1 dot healer as an outlier in terms of "deserved" potency.

I guess in the sense of fairness, either all healers get a rework that gives them depth to justify the balance between them or none do?
