What on earth is this spell meant to be good for?

The potency is so low that it's outshined by Whispering Dawn, Indom, and Sacred Soil - so why would I ever want to waste an oGCD slot on it.
If you look at a certain other Fairy oGCD (WD) which has a 60 second cooldown, that heals for 840 potency - which is a landslide better than Fey Blessing's measly 350 potency.
Since the cooldown is a whopping 60 seconds long, the low potency can't even be justified. If it were spammable then maybe...


What I'd propose is a change to make it work like an AOE Fey Union in that you have to toggle it on.

When you turn it on, every 3-5 seconds the Fairy sends out an AOE heal.
Possibly reduce the radius somewhat so that people need to be stood closer to the Fairy, and maybe reduce the potency per heal, but I reckon that'd work much better than how it currently is.
