That, is why people want %ATT, because they have that much %Boss, %Damage and Hyper and everything else. We've done the math before, and there are enough sources of %Boss etc to get us there.

Did you stop reading there? Yes, for most classes they will eventually cube a few lines for %ATT because the 233% Boss + %Total barrier is not very high. However, there are not enough sources of %Boss for most classes to get to optimal usage of all that %ATK if you have endgame aspirations. 63% ATT requires 443% Boss and %Total to make full use of it.

In conclusion, you're better off recubing away any and all %ATK on your main potentials for %Boss.
Therefore, since it's mathematically impossible for a truly endgame character (besides Xenon) to utilize all that extra %ATK, I don't see how you can dismiss a 65% Boss + %Total from Hyper stats as useless when it brings very needed balance to a naturally lopsided %ATK:%Total+%Boss ratio.

I think this graph should make it very clear. The tiny blue triangle is the only range of values where %ATK > %Boss+%Total.
x is 100%+(%Boss+%Total), and y is 100%+(%ATK).

And here's the other triangle, where %Boss+%Total > %ATK
