Banish formations

[Rocco]

Because he drains the boss's morale and prevents its skill attack (which puts a stop to your fighting)

He knows that. He's talking about the high powered players who already have plenty of LB sets and higher.

And to answer steveshort's question: they do not have Herja in their banish formation. Personally, I think having Lance and physical stunners skill atk every round with Herja more than makes up for the fact that she doesn't deal damage.
