Are you using Eos for progression? Staggering fey illumination, rouse, whispering dawn should help, emergency tactics for dropping a heal bomb on tanks and saving an aetherflow. I wouldn't even try wasting a stack on energy drain because it's highly likely to miss. Would rather cap a tank out with physick then adlo them at 90% or save adlo for if they drop below 50% HP as a buffer, to tide them over until another lustrate/physick.

Whm will always be better for bleeding edge progression because when you're undergeared, you need potency on demand, not gimmicks. Sch will likely be drastically more efficient than whm once tanks get more hp, and kill speed increases by 15-20% with better gear. As for now, whm delivers high potency with the best reliability, and since by SE's standards, everyone is still undergeared for savage, you want reliable cures, not rng.

Fairy is under healing but as they said, they balanced the curve to fit a much higher ilvl than now. Stupid I guess, but perhaps it cannot be helped.
