Please add more Water to WHM’s identity

[Shouko]

Flood! Also, (and I doubt they'd ever do this, but...) it would be interesting if they implemented elemental resistances/weaknesses (ex: Flare and Flood add water resistance debuffs in FF Brave Exvius). That would add synergy for White/Black mages. Obviously it could create a balance nightmare, but elemental weaknesses have always been a part of FF, and it could introduce very interesting new fight mechanics. Perhaps if they did something similar for unaspected casters...

They could but they won't, clearly they don't have any desire other than what the mobs are able to do and even then it's just counted as unspecified itself since there's no actual resistances, def and dmg only come into play via the wheel in Eureka sadly.

Just my 2 gil here, but isn't WHMs identity supposed to be either Holy, or nature in general?

No holy in the game, it's just elemental based, aka Earth, Air (healing, wind spells) Water, the elements are part of nature.
