White-mage is doomed - and why

[Sunako]

what this implies is that, we are already in that hypothetical "kind of overpowered" state, and it doesnt seem to me like WHM is overpowered rn.

Yes, but other healers have better MP regen too right now.

SCH can resto mana with Energy Drain + even more with dissipation.
Endwalker they only have 20% Aetherflow

AST cards restore 8% right now + sleeve draw another 8%
Endwalker Draw restore only 5% and Astrodyne 6% every 90 seconds? Yes you can use it every 30sec if you wanna waste your damage buff.
