Soon the Grand Companies of Eorza will cease their recruitment drive and testing of applicants and begin the campaign proper. Because so much lies at stake for the sake of Limsa Lominsa, Vylbrand, and Eorza as a whole, I feel the devs would be missing a great opportunity to launch the Musketeer class.

It goes a little somethin' like this.
We log in to fanfare, a slightly changed Limsa tune playing over the sea air. A bit more militaristic maybe. There are more guards standing around, idle animation different from the shuffling, must-make-it-to-the-bathroom dance the others do. This one is determined, steadfast. The adventurers' guild linkpearl glows softly, wherein Baderon informs you that something is happening in the Coral Tower. There you find Merlwyb overlooking the room, gaze falling on every new recruit as each is sworn in, takes the oath, and is given the chance to join the musketeers guild.
I'll admit it's a bit more stylized than SE would make it, and implementing Musketeers while ignoring Arcanists and Beastmasters would likely never happen, but it is a great opportunity and would fit within the lore.

Also, I'm absolutely pining for this class. I have a hard time investing interest in any of the other DoWs/DoMs simply because I want musketeers so badly.

Please SE, make this happen.
