We all know what they are suppose to do by reading the tooltip, we all know that these abilities have major flaws, but I'm curious as to what people use these abilities for compared to how situational some of the effects that they have, since most people don't tank swap unless a boss mechanic calls for it...

I generally forget about Divine Veil since Barrier effect doesn't seem to apply to PLD who cast it, SiO effect to make it stronger makes it not worth using when either MT of OT, and TBN is almost ALWAYS used when MT...
