I kinda wish Bards had a different limit break.

They just need to add more Limit Breaks. Right now we have four, each with three tiers. Change that to eight, with a potent enfeeble, buff, etc, and give each Job two options, then you can make the system much better.

Right now we have;
Tank: Def buff.
Healer: AoE Cure/Raise.
DPS: Close ranged attack.
Mage: AoE attack.

Add to that;
Tank: High potency enfeeble (super flash/etc.).
Healer: Light Arrow ranged attack (@Lv3 it can resemble something similar to Alexanders finish on Bahamut).
DPS: Massive DPS stats boost.
Mage: Crowd Control related (putting down a large snare that binds enemies?).

Now, you give Jobs two Limit Breaks based on their role. Archer (and later Ranger), for example, could have the new Healer and Mage Limit Breaks, while Bard (it is a support Job) could go with the new DPS and Tank Limit Breaks. Paladin could have the current Tank Limit Break and current Healer Limit Break. Warrior isn't so much about defense, so give it the current DPS Limit Break and the new DPS Limit Break. White Mage gets both Healer Limit Breaks, Scholar gets the current Healer Limit Break and the new Mage Limit Break. etc. etc.

I'd like to think that the main reason for putting Archer and Bard onto the healing one was to prevent an imbalance. Archer/Bard is the only physical ranged role currently, and having a unique LB would make it far more attractive that it already is, especially if it has a strong effect.

I can see Bard still retaining the healer limit break if a physical ranged LB was added along with Musketeer (or other similar role). The background information for it allows Bard to fit the healer LB quite well:

In time, their impassioned songs came to hold sway over the hearts of men, inspiring their comrades to great feats and granting peace unto those who lay upon the precipice of death.

If you wanted to equate "peace" with "not dying any more".
