Now that "thieves" got something really interesting it might prove interesting as well expanding the usefulness of the Bard class.
Bards by the group of skills and spells they have are more suited to a support-role than anything and by bringing those special abilities they have, they would be certainly more interesting playing them.
Basically that would mean bringing to the game, the inspire competence/courage/greatness which is argueably the more interesting capacity that a bard can offer to a group.
Additionally bringing bardic lore (to identify items) and countersong would be nice as well.
Here is the link in which is explained the bard class:
