Right now Astral is made up of 34% Fire, 33% Lightning, and 33% Wind.
(Banish, Dia, and possibly Holy if it's ever available, etc.)

Umbral is made up of 34% Ice, 33% Water, and 33% Earth.
(Scourge, Bio, and Shadowseer, etc.)

In the past FF games, Light and Dark were their own separate elements.

What would you prefer? Should they stay a combination of 3 elements or should they become their own element?
