There's already an oh-shit button that gives you swiftcast on all Adlo/Succor for 20 whole seconds called Seraphism.
This new skill is sort of overpowered and people are now worried that it might be nerfed because it outright overcomes the one weakness of SCH - emergency burst heal.
Stop asking for more. You're just not used to playing a different healer that doesn't burst heal through everything like WHM.
