On Limit Breaks and Summoner

[Colino]

Paladin - Grants the party "Invincibility" for 30 seconds, revives all fallen team-mates and generates a massive amount of hate.

That would be so massively broken no other limit break would be necessary.

Bard - A volley of arrows shot from Ballistae will impale the enemy causing massive damage and every debuff available

That's not how bard works. It will most likely be a pt buff of some sort like Battle Voice is.
