PLD - Skills in numbers - Does anyone have any clue?

[Alphras]

It's not as easy as that. Single target the PLD only uses one Combo, which has a high enmity modifier. The WAR (not Marauder) needs to throw in Combos without an enmity modifier at all (either every second or every third combo). If you begin throwing Fight or Flight, Berserk and Unchained into the equation it will become really complex.

On multiple targets the WAR wins in terms of enmity, but spamming overpowers is very inefficient and he will lose the mitigation from inner beast.

On the other hand comparing enmity generation is pointless, because enmity generation of tanks in this game is ridiculously high.

Edit:
As for your question. There is not really a situation where one or the other would fit better. They can both perform any MT or OT role in the endgame content. Square did a really good job at balancing boths jobs in terms of effectiveness.
