Yeah, given the rank system, EX +++ literally cannot exist. To explain +, I'll use E rank, since it is small and easy to comprehend for my maths hating brain early in this morning.

E Rank is 10

E+ Rank is 10/20

E++ Rank is 10/30

E+++ would be 10/40

Now, Ex is meant to be incomparably strong (in most cases shown), and while the ability put out here is probably EX, this cause problems:

EX Rank is unmeasurable

EX+ would be unmeasurable x 2 = still unmeasurable

It is obviously impossible to say that something already so strong it can't be compared to other ranks can be measured as double itself. I think I saw a diagram that would explain it better, I'll see if I can find it.

Then again, this is based on my understanding of +'s in the context of stat ranks (where Ex is practiaclly non-existant), so how they apply to NP ranks (where it isn't) may be different. I can't think of many + rank NP's anyway, except Thrown Gae Bolg, which is B+. Regardless, EX+++ is still a ridiculous sounding rank.
