ya 2.5 Part 2 waiting is getting on edge for 3.0 so....
What do you think the Machinist story will be about and/or focus on?
Much as I would enjoy going into Astrologian Job Story, I see Machinist having a more interesting theme to its storyline considering Machinist use Magitek as their main source of skills from creating mods for the Gun to creating Magitek Drones for support. Eorzea is still in their early years of developing Magitek so there is only a small handful of Magitek in Eorzea's daily life.
So my best guess for Machinist Job story is that it may focus on how Eorzea is handling their development into Magitek and how people handle the introduction of Magitek to their life.
