Remaking classical status ailments

[Elexia]

What about some of the new status that were in 12, like Bubble & Reverse?

Those weren't really new perse, just a different form. For example iirc, Bubble increased max HP right? That was something that's been around for a bit in various ways throughout older FF games.

Reverse for example is just a type of Absorb status, like in FFVII you had that monster in Shrina Mansion that had a physical heal mode or magical heal mode.
