Agreed, though I don't mind Swords Bards frontliners either. But if you don't have access to Swords Bard, Valor Bard is a fine choice. It's just Swords with a few penalties, though I grew to respect Battle Magic in the fight with Tiamat. Though I can't say that's of course a standard situation and it's late enough that I'd rather take the action economy of the Flourishes over the rather situational benefit of being able to bonus action attack with any bow after casting an 1 hour buff or dimension dooring.
