I'd just like to see F4 and B4, Ley Lines and Between the Lines, etc., share a button by default. I also wouldn't mind Polyglot progress freezing or reverting upon losing AF/UI, instead of cancelling all progress.

...That being said... I wouldn't be terribly surprised if they just entirely did away with the F4 and B4 requiring AF/UI, made Ice spells free outright, and made the effect of AF/UI stacks a bit more intuitive.
As such, I wouldn't be shocked if they removed the Ice MP costs entirely, removed the 10|20|30% penalties incurred from using the opposite element, and had Astral Fire increase Fire damage dealt by 20|40|60% and reduce Ice cast times by 20|40|60%, while having Umbral Ice generate 20|40|60% of max MP per tick and reduce Fire cast times and MP costs by 20|40|60%. Possibly also have AF increase Fire MP costs by 20|40|60%, instead of 100|100|100%, while increasing base costs by 25% to create the same resultant values, and have UI decrease Fire MP costs by 20|40|60%. With that, everything would use 20% per stack -- nice and simple.At present, Astral Fire stacks increase Fire damage dealt by 40|60|80%, increase Fire MP costs by 100|100|100%, decrease Ice damage dealt by 10|20|30%, decrease Ice spell cast times by 0|0|50% and decrease Ice spell MP costs by 100|100|100%.
Umbral Ice stacks decrease Ice MP costs by 25|50|100%, decrease Fire spell MP costs by 100|100|100%, decrease Fire spell cast times by 0|0|50%, and decrease Fire damage by 10|20|30%, while providing 3200|4700|6200 MP per tick.
(Yes, that'd still keep the MP values fairly pretty. You'd spend still have the same visible values and number of casts as before; you'd just have AF and UI work quite a bit more intuitively. You'd just have to slightly decrease the MP cost of Fire III or Fire I / Paradox to compensate for the 40% remaining MP on the first Fire cast, is all.)
