I dono why Divine Veil gets so much crap.

It's an extra, stacking, shield for raid-wide damage. It will automatically deploy on a Succor. Or, if the Scholar is Deploying an Adlo, they can cast it on you.
Plenty of fights past have had big raid-wides that required Stone Skin+Succor and even Sacred Soil on top of it in order to keep squishy DPS alive. Veil is fantastic for that.
