Yes but clearly since you can having 5-6 DPS pulling 100+ DPS on Coincounter with a WAR tank, killing it in under 2minutes, you don't need all that superfluous enmity PLD can generate. It's a talent that is wasted/lost on that fight.

Extra enmity does not always make up for the loss of significant damage. If you are holding "just enough" enmity to keep stuff of BLMs in the above scenario or are a PLD skyrocketing past their enmity levels, then the largest different in the fight is the lost DPS from the tank.
