I fully agree that the perfect extent of certain abilities, like Transduality for example, are completely different from even what I refer to as a qualitative superiority. Indeed, a truly transdual character can't really be said to have a "qualitative superiority" (Or even a "meta-qualitative" superiority, which is what I defined High 1-A as), because it would be above qualities to begin with. By that token, equating it to a qualitative superiority is as much of a category error as equating a qualitative superiority to a quantitative superiority.
So, if you get me a character that's essentially a perfect portrayal of Transduality, for example (Which is to say, most robust description possible with no contradictions to that status whatsoever), I'll have no issue with saying that character is Tier 0, for the same reasons I say R>F and BDE are inherently above dimensional jumps.
