Dissipation... just dissipate yourself

[Dragonhand]

Well...

Any time you don't need much more than regens for the next 30sec.
Any time you really need more single target healing from the healing boost.
Any time you want to be able to use 9 Aetherflow stacks in less than a minute.
When you die immediately after using Aetherflow, to get fast stacks to help recover.

So it is occasionally useful, yes.

The Skills have CDs you know?... so that would be me casting 6 lustrate... if you are that desperate that you need 6 lustrates... they ain't enough to save you...

Although right now it doesn't have much of a use, it may become more useful with 4.1's changes. Because Summon's MP cost is being reduced and the cast time is 3s instead of 6s, it might be worth using on cooldown. Assuming you don't have much Fey gauge.

3s is still an eternity to stay still in the same place without moving. I'm still gonna inst cast it.

Imagine if Dissapation had a very long CD (like 5 minutes) and automatically re-summoned the fairy you dropped afterwards, it could act as a viable emergency option to grab to Aetherflows like it's supposed to be.

That said, the buff to the Summon spell itself may be the adjustment it needs. 9 Aetherflows a minute is nothing to balk at.

It is... because what you want, most of the time is to EXO the tank and Indo after a big Aoe, with Sacred previously. 2 of them have 30 sec CD the other has 60s CD.
In all honesty, I only use Lustrate when main healing o2s, just to make sure I don't need help from the second healer and he can DPS as much as possible, or in o3s as second healer, during the adds because they hit hard a.f. (never completed o3s so there is no o4s experience) In any of those situations, the 45 cd on my Aetherflow stacks is more than sufficient.
