Bard does not make sense as a job

[Duelle]

Archer should've became Ranger. Every other class matches their job to a large degree, "a Bard also fights!" isn't a good argument. They could've had a base class that fought with songs and expanded upon that with Bard instead of just tacking it on to a completely unrelated class for the sake of it. It was a poor decision and they're struggling to make up for it. OP's right.

Go look at general depictions of bards. The dude with only a harp isn't the sole depiction of a bard. Otherwise Leliana (from Dragon Age), Kana (from Pillars of Eternity) or the bard from The Bard's Tale (who was no pushover combat-wise) wouldn't exist. Hell, even the bard in Romancing SaGa: Minstrel's Song was a combat powerhouse (sure, he was a god in disguise, but still).

Or make it so BRDs should play songs, like their efficiency is like 10% without singing.

The problem is BRD's songs are basically auras that affect party members. You could incorporate something like a system where songs are debuffs that can be consumed/triggered using archer skills, though. I'll throw in my Invocation system since it is also an application of songs in combat.
