"Parsed Facts" and "Ecologic Validity"

OP, if you were capable of tanking the raid boss without needing the 20% slow then the lancer was correct to forgo its use. The faster you can complete the dungeon, the better off everyone is. However, if the lack of the debuff caused you (or anyone else in the party) to deal less damage overall than the damage the lancer gained by not using it, then he was wrong and should have used it.

Well if the PLD is taking less dmg then the WHM or SCH is healing less, allowing them more time to add to DPS, which would most definitely make up for the dmg loss in the time it takes the DRG to use ONE move.

The DRG cared only about their own DPS, not the overall DPS of the party, nor the overall safety of the party.
