Any experienced, Endgame Paladin who knows how to work as part of a team would never, ever use an ability that forced a monster to focus solely on one person.

I'm sorry, but it's extremely obvious that there's very little experience speaking behind some of these things. Endgame tanking outside Abyssea is team-based. You have co-tanks. You lose hate on purpose a lot. Forcing a mob to lock onto you for some amount of time is basically asking to get your ass kicked and make your entire team worthless.
