Bard does not make sense as a job

[Aiselia]

If you are going to judge based on a preconceived notion, learn the history behind it first please.

Here's the problem: History is irrelevant. This is Final Fantasy. It's completely reasonable and logical to expect Bards to have a big focus on songs, since Bards in previous games have pretty much been all about the songs and NOT archers going "tra-la-la" in battle.

Historically, "black magic" had little to do with throwing fireballs from your fingertips and creating massive explosions with your mind. But that doesn't matter, because that's how it's established in Final Fantasy.

Historically, dragoons were mounted infantry and had absolutely nothing to do with jumping over skyscrapers to stab dragons in the face. But that doesn't matter, because that's how it's established in Final Fantasy.
