They really should just give Bards a LB that is akin to Bloodlust or something on WoW. A 15s haste/damage buff for the whole party or something. That would be more fitting for Bards since they are a 'support' role, not a healer or strictly dps.

It's obvious that the only reason they got the healer LB is because the ranged DPS LB uses magic and SE was too lazy to make one with different graphics for them.
