10k Universal MP Is Boring.

If we could specifically use something like materia to increase MP, that could potentially be an interesting form of customization. Like for BLM, having a bit more MP might mean that when things get wild, you'd be able to cast Fire an additional time without sacrificing your ability to hit Flare Star. Deciding whether that was worth the materia to have that flexibility might be an interesting choice.

But that said, I don't see anything like that happening, unless they get really wild in 8.0.

It may blow your mind that raising MP pools by using Mind Materia on BLM back in HW was actually a thing to ensure 6 Fire 4 in astral on some species (notably highlanders), and that reaching certain thresholds above on every species was strongly suggested to prevent bad tick rates making you unable to regen MP fully under umbral or just falling dry of MP and being left unable to cast anything.

Not saying that it was good execution of the system, but it sure was something. You could customize a lot more back then.

Actually, it was problematic because anyway people would follow the same meta models and builds, and all it was doing was making casuals or new players left behind because they just didn't know or cared, that's what was bad in execution. But for example if you take doh/dol even today with their stat thresholds, it's interesting somewhat that as the expansion progresses and gear goes up it unlocks more possibilities and thresholds for them to reach, potentially changing rotations, gameplay, etc.
