The Summoner. Summoners have always been my favorite roles to play in Final Fantasy games. They are able to summon incredibly powerful beings known as Primals to do their bidding. Some of the Primals confirmed to be in Final Fantasy XIV by the developers are Ifrit, Garuda, and Titan, but that’s likely just scratching the service of what’s going to be available. Those Summoners themselves pose little threat to enemies, the Primals that they were able to control in past games were able to deal not only physical damage to the Summoners’ enemies, but also nearly every element depending on which Primal the Summoner chose to enter combat with.
In Final Fantasy XI, the first pet Summoners were able to control was Carbuncle, which is the same as Arcanist in Final Fantasy XIV. That fact alone leads me to believe those looking to play the Summoner would likely need to level Arcanist to 30 for their main job.
