I agree as well, bards need a offensive LB!
a AOE LB would make more sense, since bard is on top 3 of the aoe DDs, but even a single target LB would make more sense then this healing.

While i was still a archer, i did manage to use the healing LB quite some times to save people, but now at high lvls is useless..
a white mage or scholar can very easily use a shiftcast + aoe heal which heals everyone much better(and faster) then the healing LB.
