Puppetmaster (Limited)
Puppetmaster takes the cake as the most creative and unique job that the Final Fantasy XI dev team ever came up with. Puppetmasters are able to build their very own automaton using various parts and then actually program the AI of the puppet by picking from various attachments that influence behavior.
The result is a job that can be customized to do all sorts of things such as heal, tank, cast elemental spells, or fire arrows. While it’s in a decent place now after recent balance changes, for most of its life in Final Fantasy XI it was a jack of all trades but master of none.
Still, the dev team deserves some credit for coming up with something very fun that stands out from any other class I’ve seen in an MMORPG.
Puppetmaster never really fit into parties well in Final Fantasy XI so it would probably not work well either in Final Fantasy XIV unless the devs dramatically depart from Final Fantasy XI’s vision of it.
As a limited job though, where it can function as a glorified mini-game to let you get creative and tackle some old content, now that could work.
Blue Mage in Final Fantasy XIV is still in rough shape because it doesn’t really live up to the fantasy of being insanely overpowered as a lot of its spells are underwhelming.
Puppetmaster’s appeal would rely less on power like Blue Mage, but more about putting together your very own companion to explore the world with. And in this case, as a limited job, it has room to be even more creative with parts and attachments since it doesn’t need to worry about fitting into an endgame party.
