I played bard in PvP back when I actually mained the job.

It's fun, having foes and an instant MP refresher is very useful.

Popping all your damage CDs then lining up your rotation and throwing in long shot you can dish out some SERIOUS burst on someone, and you have a jump-back through repelling shot for escaping a melee, and shadowbind to CC someone.
Not to mention the ever invaluable ranged silence.

But..outside of that..it's kinda meh. Without things like raging strikes, hawks eye+barrage there's no way you'll kill anyone unless they afk or you steal someone's kill with miserys end.

Its fun, you can have some good times on it, but I get bored of it. I'm biased though because nin4life.
