Quoting what I posted in another thread that's more specific to what's missing.

And it should have been obvious that it's missing as I've felt this way about SCH and PLD gauges for all of ShB.

As it stands now, the job would basically play no differently if they removed Faerie Gauge and just gave cooldowns to the single spender it currently has.

I think the best thing would be to give an offensive spender, that continuously drains gauge just like Aetherpact but is instead giving yourself and allies a damage buff against the Disunioned target.

They could also just make Eos the default pet, and it's Selene who comes out when you Union or Disunion and follows them, so you also wouldn't need to move Selene around to Aetherpact someone.

Paladin also has a similar problem of its gauge only being defensive, but often ends upstuck maxed out with nothing to do with it in 8 man content as the off tank. Those are design issues that should be fixed.
