I hope this game doesn't follow WoW's expansion routine.

I think zilart came with samurai, dragoon, ninja? Can't remember what cop introduced, jobs wise (summoner?) but I know for sure toau introduced blue mage, corsair, puppet master. Then wotg introduced scholar and dancer, while adoulin introduced geomancer and rune knights.

So that's 3, 1 (unsure), 3, 2, 2? Hopefully ARR expansion starts with introducing 3 new jobs, or a major update introducing 1 job and then 2 jobs at expansion.

Now that I think about it, that's quite a few jobs pre zilart (6 basic, 5 unlocks). Maybe some of them were from updates.

It's been too long...but I think Summoner was before Zilart. I vaguely remember it being close to what Arcanist is now, a Carby Wrangler. At the very least I know you can unlock the job without the Zilart expansion activated. Chains of Promathia had *zero* jobs added, it was all story and it wasn't very well received at first, depending on which crowd you were in. You're right about the others.

Zilart was Samurai, Ninja, and Summoner just in case anyone's curious
Base game did have 12 jobs though
warrior, black mage, white mage, red mage, thief, monk
paladin, dark knight, dragoon, beastmaster, bard, ranger

From the wiki
Using NA release dates for simplicity

Prior to the Zilart expansion, the standard jobs were Warrior, Monk, White Mage, Red Mage, Black Mage, Thief. extra jobs were Dark Knight, Paladin, Ranger, Bard, Summoner and Beastmaster. (FWIW I don't recall Beastmasters being in game during the Zilart expansions which is when I played, but I also am shaky on what I had for breakfast yesterday)
