Let's redefine "damage taxes"

[Mithron]

And this logic fails due to not considering actual difficulty. MCH shouldn't be doing as much damage as a RDM, just like SMN. Also all rDPS numbers being within 1% of each other is not true balance

The only time difficulty should matter is when in the same role of raid damage buff jobs. MCH isn't in the same role as RDM or SMN, it's in the same role as Selfish DPS like BLM and SAM, therefore must do BLM and SAM damage, regardless of "difficulty."
