There are similarities there to the Puppetmaster job from FFXI. You customize your puppet to play the roll you want it to. It would be cool to build something from scratch though, like a robot.
It would be neat to take all the best parts from the pet jobs in FFXI: Beastmaster, Summoner, and Puppetmaster, and roll them into one for some ultimate pet job. I liked aspects from all three of those jobs in FFXI but they all had their drawbacks.
