Is it more dps to Foe Requiem for the white mage that just entered Cleric Stance or to just keep dpsing. Maybe it is better to Mana song since Holy can quickly deplete their mp pool?

assumption: No caster dps class around, 1 Bard 1 Melee or even 2 Bards. The healer haven''t needed mana song, pretty unlikely yer gonna die while casting, however it is time away from doing damage while you are casting.

Mainly looking for dungeon grouping answers, Currently I Foe Requiem if I see Cleric Stance pop up in those situations, that might be the wrong answer though.
