How i'd fix it, rework of all the healers jobs. Fewer ocgd heals, remove redundant skills( im looking at you draw, play etc.) Remove the dot(sch could even get more) and remove repose, lucid dreaming, swiftcast, surecast and rescue, change rezzs to charged abilities with a cd of one minute.
Like as part of the rework lilies would change already on hotbar skills like cure or medica and tie misery to something else or make it a cd.
