White Mage Flavor in 6.0

[Rein_eon_Osborne]

When you have the lily system, even if you are procing them far more frequently, every single one of them would make better sense if they were OGCD skills because it makes it possible to actually weave them between other GCD skills.

No.
If anything, the last thing WHM need right now is more oGCDs because they're currently lacking available options to open up weaving windows to use said oGCDs. Add more of those and you'll only exacerbate clipping, one of their gameplay issue. WHM currently have 9 (or 10 if you count Fluid Aura) oGCD from their own arsenal and 3 from role skills, that gives them a total of 12-13 oGCD that can be weaved. Assuming that no Lily or Regen were thrown, WHMs only have 4 (5 if you count swiftcasted Glare) weave slots to fill per minute. Each lily spellcast provide us 2 additional weave slots due to being insta-GCD.

For example, if I do Plenary Indulgence (OGCD) => Medica 2 (GCD) => Afflatus Rapture (GCD) that would make more sense if it was an OGCD skill.

Medica II cast time is as long as our GCD after Spell Speed calculated in. You spend one -whole- GCD just to cast and release it. Now assume that we've made Rapture an oGCD... that would make far less sense because an oGCD doesn't roll our GCD uptime. You know what is this? It's called clipping. Please don't.

Afflatus Misery is (IIRC) an OGCD skill, which means I can snap that off between Glares. The last one Afflatus Solace is frustrating as a GCD skill when it should be OGCD like Tet. But that also highlights a problem with the single target healing on the WHM as you generally shouldn't need Cure 2 unless things are really going sideways

Again, no.
Misery is an instant GCD/spell. You can't snap that one 'between Glares'. What you've been doing so far is probably following up a fully casted Glare by an immediate Misery nuke. Solace is better off being GCD because like Rapture, make them an oGCD and you'll exacerbate WHM's clipping and leaving WHMs with far less option to weave beside tossing a Regen as their weaving/movement tool or early Aero/Dia refresh.
