Archer > Bard & Musketeer
I think Ranger as a second job is a bit too obvious, and Bard seems to have that whole bow niche covered. There's already evidence enough of gun-wielding entities in the game.
Conjurer > White Mage & Geomancer
They've built up the whole nature/earth bit with Conjurer, I think it's a foregone conclusion that Geomancer will be the second job.
Gladiator > Paladin & Red Mage
I think most people are hoping for the RDM job, and Gladiator weapon fits. I'm just concerned that most of the staple RDM abilities have already been given out.
Lancer > Dragoon & ???
I'm thinking this may be one of the jobs that they were hinting about with something new. I can't really think of a classic FF job that uses a spear type weapon which isn't the Dragoon. Wondering if maybe they'll instead go for a more pet-focused class, sorta like the FFXI Dragoon but with more emphasis on the pet.
Marauder > Warrior & Beastmaster or Berserker
I'm sure I'm not the only one hoping to see the return of the beastmaster. As much as I hope for it however, I'm thinking that if they do add it in it will be further down the line with its' own melee/pet class. My other choice would be a Berserker class with a berserk mechanic. The Marauder is already halfway there with its "in your face" style of fighting.
Pugilist > Monk & Puppetmaster
I want my puppetmaster back. It uses the same weapon type as Pugilist, so implementing it wouldn't be a stretch. The game already has automaton pets and whatnot. It clearly needs puppetmaster! PUPPETMASTER! (I think you can tell what my main in 11 was).
Thaumaturge > Black Mage & Time Mage
Going with Time Mage because the style sorta fits with Thamaturge. It could also fit well with the role of being a buffer/debuffer, as outside of the SCH pet I don't think there's a reliable way to keep any forms of skill/spell haste up.
Thief -> Ninja and Dancer
Thief into Ninja is one of the most predicted upcoming class/job combos for obvious reasons. I'd choose Dancer as a second job because again, as we know from FFXI it's very similar with the dual wielding of daggers. Alternatively I could see them adding in some sort of Far Eastern class which would have both Ninja and Samurai as the jobs.
