They should just rework Whitemage back to how it was before of Shadowbringers with 6.0.
In shadowbringers it made sense out of lore reason to massively increase the whm's affinity towards light magic and turn them basically offensively into pure light mages, whose affinity towards light absolutely overshadows thei affinity towards wind, earth and water.
In regard of water has been the whitemage always the poor skill design oversight, back before shadowbringers, where whm's had only 1 single lauchable water skill, annd it wasn't even a magic spell based on the typical spell naming convetions of FF, while lots of enemies thew at us already water magic spell, where you asked yourself only - why can this stupid trash cast Waterga/Aquaga or lower and we learn for 80 lvl still no fu...... Single water spell?


I hope, once all classes get for one day their final major endgame redesigns for Lvl 99 content, that the 8 classic elements will be findable among all classes somewhere and the others

Fire > Blackmage/Sorcerer
Ice > Blackmage/Sorcerer,
Thunder > Blackmage/Sorcerer
Wind > Whitemage/Priest > return of Wind/ra/ga/ja
Earth > Whitemage/Priest/Redmage/Elementalist, return of healers Stone/ra/ga/ja and we should get to see Quake/Shockwave
Water > Whitemage/Priest/Redmage/Elementalist , implemention of Aqua/ra/ga/ja for WHM, water replacing ice for RDM, making ice more a speciality of BLM
Darkness > Dark Knight/Shadowbringer/ Astrologist/Oracle
Light > Whitemage/Priest, Scholar/Sage, Astrologist/Oracle, Paladin/Crusader
All Elements > Summoner/Ritualist based on active High Summon, Ninja/Shinobi based on Finger Sign Combos, Monk/Champion based on Stances/Attunements

Thats how I do see the elements among the classes that do use elemental powers by class design
