A friend asked me this question, after seeing that the planar ornaments were supposed to be on HP/DEF. I never really questioned it since everyone went with it, but what's the reason? I can understand it for her BA and skill since they're not the bulk of her damage, but her EBA also scales off of her ATK. Does her ATK just scales worse than crit values in general? Or is her EBA too negligible compared to her elation skill?
