Personally since both Dissipation and Fey Blessing have been brought up in here, I feel that they should do a couple things:
Summon changes:
Summon/Summon II become instant abilities with a 10 second cool down like SMN has for their Egis. Summon Seraph can only be used while a pet is summoned or while under the effect of Dissipation.
Dissipation changes:
Dissipation desummons the fairy and gives us 3 stacks as normal, while increasing [the potency of Aetherflow abilities and-- Maybe on this, but that might be too much] healing GCD spells.
Aetherflow usage under dissipation now charges the fairy gauge, giving 15-20 fairy gauge with each skill use instead of 10.
Auto-Resummon is removed with the changes to Summon, Summon II and Summon Seraph.
Upon using Summon Seraph, Summon, Summon II the effect of Dissipation ends [It still has its normal duration of 30 seconds.]
Fey Blessing:
Cost increased to 30. Potency increased to be about 250-350 AOE potency, relative to healers. Cool down reduced to 10 seconds. The cost would be its main limiter.
To me, this would make the skills much more synergistic. Maybe too powerful, but I think the skills make more sense this way.
As an additional Idea, ive been toying with what could replace energy Drain, without being broken, while making the kit more connected:
Tactical Conversion:
While having Aetherflow stacks, Tactical Conversion becomes Fey Boost. While not under the effect of Aetherflow, Tactical Conversion becomes Fey Covenant Cool down of 20 seconds.
Fey Boost:
This action cannot be assigned to the hotbar. Can only be used under the effect of Aetherflow.
Cost: 1 Aetherflow.
Grants your fairy 10 Fairy Gauge. Increases embraces potency by 10% for 20 seconds. [Will actually give it 20 fairy gauge, because of its Aetherflow cost.]
Fey Covenant:
This action cannot be assigned to the hotbar. Can only be used while not under the effect of Aetherflow.
Cost: 30 Fairy Gauge.
Grants you 1 stack of Aetherflow.
