I'm convinced there's a good Bard design out there that somehow keeps the original 1e idea of a part-Fighter, part-Thief chassis with music and sonic abilities yet which starts at 1st level like all the other classes, but I've yet to either see it or think of it.
For LNO I found that opening the concept of the Bard to all kinds of artists (as well as the mechanical chassis of a Psionic type class) made for pretty decent core idea to build a class around.
Not only covers more potential character types, but it helped make it easier to develop a core identity that these characters can unite around. With it using the same Psionic type mechanics, all that was necessary was finding a means to differentiate it in comparison to the other Psionics, and that wasn't too difficult.
In LNO, Bards operate in a relatively unique niche whereby they make use of both Mana and Stamina simultaneously to empower their psionic abilities. (Whereas the Monk and Hedge Mage use Mana and the Mystic and Pilgrim Stamina, exclusively)
Due to how both energies are raised, this naturally inclines Bards towards the "skill monkey" direction, but players also have the option to neglect that purisuit and instead go for one or the other, which will make their psionics less potent, but will still allow them to be viable as they'll be able to act more as a conventional mage or martial type.
And meanwhile in the scheme of all the classes, Bards run a versatile gamut depending on how the player wants to play.
String Sworn is the more classical Bard experience, mixed with some healthy dashes of Kung Fu Hustle type shenanigans, but you could also go for
Woad Scribe, using paint to buff your allies and manifest wonderful defensive "living" art pieced, or you could go
Skald and literally insult your enemies to death.
And then, because I couldn't resist, theres the
Game Master, sort of a Bard take on the Wild Magic Sorcerer in 5e, who not only leans on the games-as-art angle, but also brings the more overt thief-like qualities into the class.
While it may not be ideal for everyone, the more I kept working at this design the more it kept making sense, to me at least, for it to be this way, so, YMMV.
