Conceptually, I love it. Ordering the pet to focus heal someone while I tend to other things is clever job design. Remembering to cancel the tether to conserve gauge when it's not needed or re-apply it after using another pet skill makes me feel smart. It's like a very small hit of actually being the battlefield tactician that was sold to us in the job lore. I know about the manual Embrace targeting in ARR/HW and this seems like an okay refinement of that system... less control overall in exchange for not having to bonk an Embrace macro after every cast during hectic action.

Practically? It's piss-weak and sucks. It barely heals for more than Embrace, and to charge gauge optimally you have to deal with extremely annoying drawbacks like not spending Dissipation's aetherflow charges until the fairy returns, which is almost always not worth it since it entails not dumping E.Drains during a burst window or delaying the use of your regular Aetherflow.

If Fey Union healed for more, if Fey Blessing were back on the gauge, and if the gauge awarded 150% for dumping during Dissipation instead of nothing, it would make a much more satisfying gameplay loop. Burst window goes off, you spend 6 charges under the Dissipation buff and get rewarded with 90 gauge instead of a big fat 0, then the fairy comes back and you pop off with powerful fairy gauge heals to quickly bring everyone back to safety before more damage goes out.

Instead, you don't get to choose when to Dissipate at all, because you need its laughable +healing buff to make giant Spreadlos for the un-fun 'kitchen sink mitigate or wipe' mechs they keep adding to force the DPS to press AddleFeint. It's all just ass-backwards from what actual fun healing design should be.
