History of the Gunner job.

Or just the heretics like someone said. The pope can say what he wants, there are always outcasts in a city

The problem is, housing an entire guild of heretics in a city whose stated purpose is the eradication of said heretics... that is downright suicidal if you ask me. Talk to the wrong person, dress in the wrong clothes, and you just bought yourself a one way ticket to being burned on a stake.

There is a reason why all Heretics in our own world went to ground or fled Europe during the 13th through 19th centuries. It just wasn't safe to be a heretic, Jew, or Muslim during those times in Europe. Likewise it just wouldn't be safe to be a practicing Dark Knight, Tempered, Garlean, or what have you within the confines of Ishgard's Holy See... I mean just look at what almost happens to the player during the Coerthas segment of the Main Scenario Questline.
