As much as I understand WHM, I think that the issue regarding the Afflatus Heals is over-rated for the panic it is. I took a step back these past couple weeks and I rethought about the WHY.
Instead of worrying about the past, I looked at the Afflatus set of Heals. They’re basically substitutions for Medica/Cure II except are Instant so that you aren’t clamoring for a Swift during a mechanic. As far as movement goes, WHM should be ok if it’s using Afflatus correctly so it isn’t a direct DPS Loss, but a positive. If you use the Afflatus Heals where you need to heal,it makes it worth it.
