Critical issues that need to be addressed

[Atreus]

This can only work with certain abilities, not others. There is no way to "scale" something like Benediction, whose entire existence is based on it being the "oh crud" button giving an instant-cast 100% heal. There is no way to "scale" a tank having a skill granting invulnerability. And good luck making DPS classes equal in usefulness through scaling when one has multiple AoE spells and the other doesn't have any yet.

At a certain point we need to say fuck it. Again, there are creative ways to do this. People are too worried about it "becoming bad" when it already is. Full stop.
