Dissipate overpowered?

[Cynfael]

You cannot click off Dissipation; you are locked out of resummoning for 30 seconds.

This ability simply isn't good. I can only imagine that the devs conceived this as a sort of WHM mode for SCHs, but the loss of the fairy combined with the necessity of blowing the MP and usually a SC to resummon it make it more hassle than it's worth.

I don't need more Aetherflow stacks with which to healbomb people; I'd almost always rather have a second source of heals and a cleanse that's AoE and not tied to my GCD. If I want a 20% healing buff, I'll summon Eos.
