Is Dissipation really that bad?

[MercuryAcetylene]

The thing I'll never have:

Dissipation: Orders your pet away while granting you a full Aetherflow stack.
Also grants a buff that increases healing magic potency by 20%. Aetherflow spent while in dissipation will fill fairy gauge at a rate of 20 instead of 10. Using aetherflow outside of a fairy summoned or dissipation will have no effect on the gauge. Your next Summon or Summon II is instant cast. Buff ends after 30 seconds or when your next Summon or Summon II is cast.

too bad spending aetherflow while under the effects of dissipation (faerie can't be summoned) does nothing to the faerie gauge.
