My guess is HW will give you increased FATE xp from 50-60 once you get your first 60, providing you with something to smash on while you level other jobs and are sitting in the dungeon queue. That's just my guess, though. I don't know if it's actually the case.
You're talking about the armory bonus. It's not active upon hitting max level, but on every class below your highest (for instance, if you have lancer at 53 and blm at 51, blm will get the bonus).

It's also a 50% increase to mob xp and fate xp.

Which doesn't change the efficiency of HW fates vs ARR late game fates due to how close their initial xp values are.
