Considering they gave Machinist its own Automaton (Queen), that Mammets look very similar to FFXI's automatons (which could be a good thing though, I don't think we saw them in really serious combat aside from some dungeons and Lord of Verminion) and the dev team is kinda averse to pet jobs, I'm not sure Puppetmaster would come in this game as is. They would probably prefer renaming it and giving it different abilities, but I'm not sure that will happen, if they don't already believe Machinist is this game's Puppetmaster already.

That would be neat if it happened,though!
