In a demonstration video that’s included below, it’s the Black Mage in the party who initiated the Limit Break, triggering the Meteor ability. If the party Paladin triggered it, the effect would have been different.
From this, we can tell that one of BLM's limit break is that massive meteor strike. (Just like original op trailer for FF 14) According to FF14 special session, Monk might gets Tifa's Final Heaven.... (I hope it is real)
What would you like to have for other jobs' limit break?
I wonder if Yoshi-P would consider adding FF 7 Cloud's Omnislash for Paladin…
