WHM Lily suggestion.

Either as a retroactive spell or a new one in Endwalker, why not make a new Lily spell for attack purposes?

Afflatus Shock
Cast: Instant
Recast: 2.5s
Deals unaspected damage with a potency of 250
Lily Gauge Cost: 1 Lily

This can allow WHMs a spell to use to weave abilities or to move for mechanics without having to overheal or overwrite their DoT. The downside is that this action has less potency than Glare, so it's not a DPS gain if you can cast a Glare, and also doesn't nourish the Blood Lily.

Alternatively, Afflatus Shock CAN nourish the Blood Lily, but the potency of Afflatus Shock and Afflatus Misery can be reduced to 150 and 700, making the overall potency of three Shocks and Misery 1150, which would ultimately be less than four Glares, again preventing players from using Lilies solely for damage.

If the second method is done, then I suggest another spell:

Afflatus Paradise
Cast: Instant
Recast: 2.5s
Restores own HP and the HP of all nearby party members.
Cure Potency: 550
Can only be executed when the Life Lily is in full bloom.

The Life Lily can be the counter to the Blood Lily, with Afflatus Rapture and Solace nurturing the Life Lily instead of the Blood Lily.

IMO WHM also needs a second Lily skill that's a 1 lily AoE DPS. We've got 1 lily single target and AoE heals, and a three lily DPS, and with the skills your proposing that's the only one that's left out.
