Endwalker White Mage has Issues

[Ryme]

My thoughts are that Misery should cost 2 blood Lily stacks instead of 3 (though you can still bank 3).
This would keep Misery at a damage loss (albeit only 30p over 3 GCDs) in a vacuum, but placing Misery inside most raid buffs would net an overall damage gain. It would also be a minor buff to WHM’s mana economy, as it means more Misery casts overall.
The cleave damage would need to be adjusted to suit, but that’s a minor issue overall.

As for Liturgy of the Bell, I think it would be worth taking notes from Sage’s Panhaima.
Have it apply 5 stacks of the healing effect to each member individually, which are consumed for healing when struck.

I think these are very interesting fixes. Misery only needing two stack would probably feel a lot better to play, if for no other reason than casting Misery just feels fun so casting it more would just be more fun. This actually leads to a higher damage increase as well as opposed to my fix of 1300 potency as it would come out to be 1350 potency every 1.5 min. I actually think this is a much more solid change to the spell, it would also give whm more ogcd options for moment as well. Though I still think Misery should be dps neutral in this example even if its only 30 potency, it just makes it cleaner and simpler when comparing it to glare casts.

Your proposed Liturgy of the Bell is a good fix, but I think it's unlikely that square would go that direction as they seem to want it to be a fixed position healing area like asylum. Though this doesn't really address the hp fall off when it expires which when it happen makes the spell feel pretty bad for a 3 minute cd.

What troubles me most is that a lot of WHM's popularity is because SCH and AST are stuck with gimmicks and players just don't find them fun, so WHM or Sage is their only option. Not because WHM is good. However, SE will likely direct all their attention to SCH and AST to try and increase their popularity and as we've seen in the past, they do this by buffing the class until players start picking it up again, rather than needed reworks.

Personally, I don't actually think its a problem if the other healers get most of the attention, they are more complicated classes both to play and thus to balance, whm already has a very solid foundation to work from. My big problem is that the issues whm is facing, however minor or major they may be are bafflingly simple to correct. Such as glare going to 310 but misery not going to 930, or glare being 1.5 sec cast but holy still 2.5, just number tweaks. Its like they just forgot how their class worked going into Endwalker.
