Bard is an exceptionally good Damage Dealer job, with very good damage and a potential 100% uptime on their target (meaning, if you're good enough, you never have to stop attacking a target, even when most other jobs might be forced to stop attacking, such as when needing to dodge an AoE). Their "support" status only really comes into play with Mage's Ballad and Army's Paeon, which slightly reduce your damage output in order to improve nearby ally's MP and TP regeneration (respectively). These songs have a roughly 3 second cast time, after which you are free to return to dealing damage as the buff persists so long as you have the MP to sustain it. They also lack a damage-dealing Limit Break, but I can confidently say that having a Bard around to use the Rank 3 Limit Break: Pulse of Life has saved an otherwise unsuccessful boss attempt more than once.

If you try out Bard and still dislike it, the Musketeer is a class that will be released in the near future. Given that it focuses on the use of guns, it's fairly safe to say it will also be a ranged damage-dealing class like the Archer, and may better appeal to your tastes (though what job[s] will be attached to the Musketeer is still the subject of a lot of friendly debate).
