Future Jobs

Free Companies can obtain the ability to summon Full Primals (1 time / defeat of it in FATE form (Not Instance form)).

Good thing we've all got the Echo, else we'd be "Touched Ones" awfully quick :P

With ACN, it looks like there will be the trend so that each class unlocks 2 jobs. Judging on what weapons they use:

GLD: Blue Mage DD, honestly GLD is so tanky, it's kinda hard for it to branch off into a DD job
MRD: Dark Knight DD, since MRD uses 2h weapons and already can drain HP
ARC: Hunter or Ranger DD
PUG: Puppetmaster Pet DD
LNC: No clue what other jobs use lances, except maybe Samurai
CNJ/BLM: Geomancer?

Ninja and Dancer (and Thief, if 3 jobs end up linked to a single class) could branch off of a dual wield class
Corsair will likely branch off of Musketeer (the most likely next class to come out)

YoshiP also said jobs liked Red Mage would be "advanced jobs," requiring you to have both WHM and BLM unlocked for example.
*Note, this is mostly speculation

Seems to me that dark knight would be obviously MAR/ACN. Anarchist is the only caster class with the right spells. Ruin, Bio and the closes thing to drain that there is.

Now the fluffy summon is a bit awkward but an ability to change the summon to something darker would work. Though its not true to FF11 DRK in many games this type of class has a minor pet of some sort.

Traditionally, DRK was Warrior + Black Mage. And I think you're thinking of Death Knight from WoW and (forgot the name, was in EQ1, had Necromancer abilities on a minor scale), neither of those are Final Fantasy and are a bit further a departure than any other job comparison from FFXIV and earlier games. A DRK with a pet just wouldn't fit, especially if it was something "dark" like undead, since DRK have more of an affinity with traditional schools of magic rather than necromancy.

Basically, you want to look at:
A) How would it fit in FFXIV?
B) Is it in FFXI? If yes, how would it be similar? XI is already in MMORPG format, so playstyle would likely be similar.
C) Is it in FFI-XIII/offshoot FF games? That's what Jobs are: powerful class upgrades that fill a niche while being nostalgic.

Personally, since someone said machinist and commented on "Called Shots." I would rather see a Job added to Archer that is a Debuff Class. Something like Arcane Archer that has damage over time abilities as well as some abilities to "Slow," "Weaken," or even "Freeze" enemies. As to how it fits in the game? Well Archer already has a few abilities that goes with the ideas like "Blunt Arrow," "Venomous Bite," and "Windbite" and adding in a little Thaumaturge + Archer quests to give a background in combining the Classes seems to stay in character of the world so far.
