Cannoneer. Dragon Quest X has a "Pirate" vocation that summons Cannons that it uses to do its skills which I feel is something that can work in XIV. The firing line of a Cannon in DQX is pretty wide and forgiving and since this game loves its similar circular boss arenas they would be perfectly viable. Probably would be problem with how XIV hates gimmicks on its jobs or "pets" so it'll never happen but I dream of a day when they'll be unique again and we'll have fun new ways to play.
