I'm not sure how you're opposed to not sitting around waiting for the WHM to stoneskin everyone or doing it yourself to everyone. Nobody's suggesting a nerf. It would simply condense 4/8 casts of buffs into 1, just like protect is not only aoe, but with the WHM trait also includes shell even though it traditionally isn't that way in FF games. The devs just realized that healers will always put those buffs on everyone so why make them waste time casting repeatedly? Entirely the same situation here (when not in combat).
