This suggestion is based on the assumption of a major role skill rework that can accommodate the loss of Protect as a role skill.
Basically just the sort of thing I would like and would expect to be the most likely sort of changes and addition to WHM in ShB.
Main Lily changes
Lilies are generated by Regen, Medica and Medica II, or by hits received via Shell.
Lilies are spent when using Cure, Cure II, Cure III,Tornado or Quake.
1 Lily = Cast time of Cure/II/III reduced by 0.5s
2 Lilies = Cast time reduced by 1.5s
3 Lilies = Cast time reduced to 0
Protect
60s cooldown. Instant cast oGCD.
Bestow a 5% damage resistant buff on all party members in range for 30s.
Additional effect: Physical damage received by targets has a 25% chance of granting them a confession stack.
Shell
30s cooldown. Instant cast oGCD.
Bestow a 10% damage resistance buff on target for 15s.
Additional effect: Magic damage received by target has a 50% chance of granting you a Lily.
(Shell/Protect would stack with each other, both inserted in before level 50 somewhere, before Lilies or Confession stacks become available, so the traits that introduce those would introduce their additional effects.)
Tornado
Replaces Aero III whenyou have 3 Lilies. Consumes all Lilies.under the effect of 'One with the Elementals'
Deals wind damage with a potency of 80 to target and all enemies nearby it.
Additional Effect: Wind damage over time - Potency: 50 - Duration: 24s
Additional Effect: Reduces cooldown of Asylum, Assize, Divine Benison, and Tetragrammaton by 10s.
Quake
Replaces Stone IV whenyou have 3 Lilies. Consumes all Lilies.under the effect of 'One with the Elementals'
Potency 300 damage to target.
Additional Effect: Reduces cooldown of Asylum, Assize, Divine Benison, and Tetragrammaton by 10s.
New Trait: One with the Elementals
Expending 3 Lilies on a Cure/II/III spell grants you the effect of ‘One with the Elementals’.
Under the effect of ‘One with the Elementals’, Stone IV is upgraded to Quake, and Aero III is upgraded to Tornado.
Duration: 15s
Bonus new Trait: Freecure II
Grants a 50% chance that after casting Cure, the MP cost for your next Cure II will be reduced by 50%.
Grants a 25% chance that after casting Cure II, the MP cost for your next Cure III will be reduced by 50%.
Duration: 15s
(This is just because the current freecure trait is pretty much useless above level 50 or so. Making it more likely to trigger in some way, even with decreased effect, would make it more relevant.)
This would give WHM some useful utility in Shell/Protect, and the other healers losing Protect would give WHM some edge over them. They wouldn't complicate the job at lower levels, but would allow them to compete given the loss of Protect as a role skill.
They would interact with their Lily mechanic post 50, which in turn would be useful in granting mobility.
It gives WHM some (minor) mitigation utility without making them a shield-healer, and makes use of the Shell-Magic/Protect-Physical dichotomy without actually worrying about damage types as far as the rest of the party is concerned.
Experienced players could time their Shells/Protects for more effective mitigation, but the cooldown is forgiving enough to use as soon as it’s available and you’ll still at least benefit from the Lilies/Stacks, so it wouldn’t make WHM more difficult to play.
The effect of reducing oGCD cooldowns is maintained via Quake and Tornado, but is a trade-off. You can either expend Lilies via short-cast/instant Cures, for quick mobility, or you can be more strategic and expend them on a little more DPS and get your oGCD’s a bit quicker. The quick Cures would be your modus operandi to start with, rolled back to level 50+ content, before you gain Tornado and Quake around the mid-late 70’s. This would in effect add a layer of complexity of the job, that could be seen as making it more difficult… but really it just means that if you don’t need the instant Cure, you can DPS instead and still gain some benefit by regaining your oGCD heals quicker.
The lilies now improve the function of the Cure spells, granting mobility and speed, and in turn lead into your pDPS boost and utility in oGCD reduction.
