archer is mostly about fitting in and overcoming racial bias through the lens of a mi'qotte archer who gets no respect and open disdain from an elezan. the bard class quests put you with an archer of great renown who has stopped taking pupils until your character arrives and expresses an interest in his music rather than his archer skills.

That's the best spoiler-free synopsis I can give of that class route. I haven't leveled any other class to 50 yet. It wasn't bad.
