I was going to say maybe the SCH is DPS only outside the occasional Lustrate and Adlo on Prey, but there's no way they'd have no overheal if they were Adlo'ing Prey so maybe they just never leave Cleric stance and the WHM solo heals most of it with fairy assist?
Well, the first Wild Charge is skipped entirely so pre-pull Stoneskins absorbs the first double Prey. HL+Charge is immediately before the adds so can just adlo to heal off the damage? No real need to immediately heal the raid here. Only 3 total Preys go out on this phase as well with that pacing. Imdugud Prey's must just be dealt with Stoneskins to keep that SCH overheal so low. The WHMs overheal is from Tank Regens + Med2 as a single GCD response to raid damage I guess.
One of these nights we're going to be bored enough to try this.
I want to do this. I still need those tank boots on Soapy for vanity~
