New Class/Job Tree PredictionsFollow

Gladiator - Mystic Knight/Rune Fencer
Whatever you want to call it, this class has been leaning more towards the Magic Defense side of tanking in recent FF entries (FFXI, Bravely Default) so their skills would probably mesh well with the Gladiator's skills.

Pugilist - Dancer
The support side of the Pugilist class. As someone has said before, they could use their stances to perform different dances for either buffing, debuffing, or healing their allies (whichever route they want to go in).

Marauder - Berserker
The offensive Marauder. Berserkers will focus moreso on boosting their attacks to deal massive damage in short bursts.

Lancer - Templar
Templars would focus on inflicting debuffs by using combos to cause a wide variety of status effects on foes.

Archer - Ranger
DPS Archer.

Conjurer - Geomancer
There aren't really too many classes Conjurer could branch out to except Geomancer and Elementalist of which the latter basically acts like a CNJ. They could focus on using the land energies for attacks and they should also get staves that look like bells.

Thaumaturge - Time Mage
Haste, Slow, Gravity, Float, Countdown, etc. Yeah, Time Mage has a LOT of potential and would be more of a support type THM.

New Classes
Musketeer - Corsair and Chemist
Corsairs seem like pretty much a shoe-in for the Musketeer class considering where the guild is and what they are. Chemist would add another healing class that's greatly needed.

Scout - Thief and Ninja
As an above poster said, Dual Daggers that turn into Dual Katana for the Thief and Ninja job. Thieves would focus on positional DPS like Pugilists, with more emphasis on support/debilitating skills and Ninja could be more of a DD with Ninjutsu.

Fencer - Red Mage
Red Mage would be a class that needs to balance using Physical and Magical attacks to make the most of them.

Ronin - Samurai and Swordmaster
Samurai would have an emphasis on long, complex combos for massive damage while Swordmaster would be akin to the Bravely Default and Tactics Ogre (as well as Dunban from Xenoblade) class and be more of an evasion/parry tank.

Shaman - Druid
The 4 Heroes of Lights crown could return in this game and could play more like THM in 1.0 in that they'll be a healing class that drains life from themselves and others to heal their allies.

I agree with most of these except

Archer -> Bard and Ranger
Conjurer -> White Mage and Geomancer
Gladiator -> Paladin and Thief
Lancer -> Dragoon and Templar
Marauder -> Warrior and Dark Knight
Pugilist -> Monk and Puppetmaster
Thaumaturge -> Black Mage and Time Mage

New Class -> Ninja and Samurai
New Class -> Red Mage and Rune Knight
Musketeer -> Corsair and ???

Did no one notice the buccaneers or whatever you wanna call iut in coral tower in limsa? or that thycred weilds a one handed dagger with SHIN PADS?!? to me Ninja is going to be a huge option, and also in a cutscene where the Judges are from whatever that land is, the red one weilds a huge GUNBLADE KATANA, SE is defintely giving us clues to what they have planned, im as excited as everyone else in this forum about the possibilities. Other things i'm hoping for is that the correlations we find in game are going to be true later, like at a falls in gridania, i talked to an NPC who was a SAGE which to me almost confirms SE knowss whats popping out next, but hopefully we aren't all waiting too long, especially you 1.0ers :c
