Ideally what you want to do is dedicate one healer (by healer rather than debuffs on the healer) to pick up the damage down debuff and the other to pick up the phys debuff. This way you preplan out which healer is going to focus on DPS and which healer is going to focus on healing taking away an unnecessary variable and creating a constant. Ideally you want your SCH to be DPSing for double hands DPS because bane is strong, so you don't want your scholar to have the damage down debuff. Having your dps run around is a potential dps loss at this point, especially since healers can safely sprint and have no immediate requirement to heal after wash away. The same applies to when the debuffs come out during double hands
Later on in phase four, two damage down debuffs come out opposed to one. What you want to do here is have one healer assigned to each side so people are not confused so both damage downs end up on the healers (prior to this the healers should put on dots though). One of two DPS will not have a debuff these should be the ones picking the debuff off the tanks.
Hope this helps
