Why did square enix do this to bard?

Looks like the general consensus is:
Bard's are too good to have any other LB (between the ones we have now to choose from).

As it was said before, a Bard with a melee class LB would completely wipe DRG/MNK from virtually everything. If it had Caster LB, SUM would also probably be ran off, leaving your BLMs and BRDs. BLM only because it has better AoE capability than BRD. BRD has like grade B solo and AoE DPS, has Silence, and provides TP/Magic Resistance Reduction/ MP with only a 20% decrease in damage. So.... yep! Healing LB for ya.

Funny thing is Bards are almost always meant to be support classes.
