No it should be the other way around.
The way the heroes are designed now you can never balance healing vs. damage ever.
The problem is that naturally damage will be higher, the higher the player skill gets.
But with the exception to Ana this is not true for healing.
All the other healers do the same amount of healing, regardless of skill.
Depending on how we balance healing vs. damage we have the awkward situation that in bronze noone ever dies because people are not able to out dps the healing and in GM healing is worth less and less.
We kinda see this in OWL now with the single heal comps.
On this high level the dps are so good that they simply kill so fast that healing does not really matter anymore. The only form of useful healing to a dead target is rez.
So we need all healers reworked “Ana-Style” where skill directly impacts the amount of healing you can do.
