Well I main Bard .... I always try to make sure I support my party when I can (and ALSO do good damage, as good as I can as a bard obviously).

Honestly I hate bards who are all "gotta be top deeps" and then just ignore that they have support skills, like? Why? Go play MNK or something if you want to be top DPS and not support your party.

Anyway if you want to play Bard instead then do that. Practice will get your DPS numbers up, even while supporting the party.
