All of those suggestions are just way too OP. Healers are like the one set of classes that are actually well balanced.

Sacred Soil is just fine where it is, unless you are DPSing too haphazardly or your party is just getting hit by multiple mechanics, there is no reason you shouldn't have the necessary Aetherflow stacks to pop Sacred Soil whenever you need. Deployment tactics is also good where it is to be able to Adlo shield the party every 60 seconds? Kiss healer balance goodbye. Same with Whispering Dawn, plus it fits nicely with Rouse at it's current CD, shortening it would be a bit of a pain. I wouldn't mind a change to Dissipation, but I believe yours is too lenient. You should be penalized for using it by not immediately having your fairy return. That said, I do wish the rewards were a bit greater for that sacrifice. I... don't even know what to say about a damaging Silent Dusk. Call me set in my ways, butt Fairies should not being doing damage directly or indirectly. I suppose I could see a 2% increase to Fey Wind, but I'd rather just see a rework of Selene to make her more support oriented overall.
