I find in raids dissipation is a great recovery tool if you just ressed and need to stabilize your mana and aetherflow stacks if your lucid dreaming is on cooldown. With 3 second cast on summon you spend basically 1 GCD to summon, rouse and whispering dawn if needed then dissipate and spam aetherflow stacks on ED. Hopefully aetherflow comes back off cd and with 20% healing bonus you can supplement healing with succors.
