In thinking of how the merit Aura Steal was created for Thief, I want to recommend a merit to alter Provokes design when used by a Paladin.

The concept would be to convert Provoke from a direct action against the target monster to an area affect that targets party members for the purpose of transferring enmity from them, much like Accomplice or Collaborator. I'm not sure how potent the adjustment should be made if were worrying about game balance for other jobs. My initial mindset for this was for the merit to be broken down into 5 levels for 20% Enmity transferred per merit to the Paladin for a 100% full enmity wipe for party members in range at 5/5. At the recast rate for this ability it would make it possible for the PLD to hold mobs from other frontline damage dealers more reliably.
