I think those videos are a good example of how PLD should be played in Alexander, compared to how people are actually playing them. PLD Sword Oath DPS isn't far off from WAR/DRK OT, and those PLDs are sitting in Sword Oath for a lot of the fight. They're also having the WAR open the fight instead of the PLD, so when it's time to swap the PLD doesn't need Halone for enmity. There isn't going to be much of a difference in DRK/WAR vs PLD/WAR in damage, and the PLD group has access to 2 Halloweds in such a long fight.
