Dissipation vs Divine Seal

[Parawill]

you forgot to metion that divine seal is only WHM ability. AST has ZERO cooldowns to increase healing potency.

The OP also forget to mention that a White Mage's healing is heavily restricted upon the GCD system. Albeit that now we have Assize and Tetragrammaton, our bulk of our healing comes from GCD, whereas Scholar's healing is split between GCD, off-GCD and Fairy Support.

As mentioned by Yoshi-P himself though, the skill was intended for aetherflow stacks with a bonus to healing potency. I can agree it's currently not the greatest cooldown, but it doesn't warrant (not directed to you) having Divine Seal nerfed to "-1%" healing O_O
