Dragoon is extremely mobile and currently one of the top dps depending on gear. It's also got pretty good survivability as long as you learn to dodge.
BLM is my fave although I don't have all the new spells yet. I love it personally despite my myriad of derps in timing for dropping leylines lol
I would like to point out, since you are a bard, that without YOU, healers, melee dps would be in a crap ton more trouble in hard fights. So don't give it up too quickly, ok?
