On Fey Blessing...

Dissipation is actually really nice at the end of a pull. Use all your stack during a pull. Use dissipation before the last add dies.
and Voila, full stacks and a boosted adlo before the next pull.
Works nicely during boss transitions too.

After digesting some of the responses in this thread, I've actually flipped 180 on Dissipation's use in dungeons. While its issues in trials/raids are unchanged in its need for planning (and painful lack of energy drain), it's actually been helping a lot with wall-to-wall pulls in dungeon duties. You burn your first three stacks on ogcd heals (one of which should be excog) while using Art of War, pop Whispering Dawn, then dissipate for three more lustrates to handle the encounter. It gives a lot more wiggle room for adaptation, and since you don't have to waste the time to resummon the fairy it doesn't slow you down anymore. Alternatively if you know a "big" pull is upcoming, you can dissipate during the last few mobs and start the next fight with six stacks.

While I still don't like the theme of Dissipation, the fairy resummoning at least makes it feel comfortable when you use it aggressively.
