Aetherflow Gauge: It would be nice to integrate the cooldown of Aetherflow on the gauge (edges could fill up or something like that). As a bonus, this can also help with the Quickened Aetherflow feedback.

Dissipation: I can't for the life of me find a good use for this outside of VERY situational scenarios. Especially as it requires you to summon the fairy back at the end (so that's a Swiftcast + mana cost).
Proposal: Have it increase damage as well by 20% and/or automatically bring back the faerie at the end of the buff's duration.

Deployment Tactics: Very situational and constrained use for it, especially now with increased cost for shields.
Proposal: Allow it to spread Excogitation
