New Jobs: Cross Class Skills? Thoughts?

[Asheilin]

Its something I've been thinking about quite a bit, and earlier I a XIV youtube video I watched mentioned their guesses. Made me wonder what everyone is thinking about this.
I am assuming, of course, that they GET cross class skills despite being classless.
I'm going to list my thoughts, and reasons why. Hopefully, everyone else will too!

Dark Knight:
Marauder: Firstly because it wouldn't make sense to not be linked to a tank, and I personally don't see it meshing with Paladin the Holy/Light centric. Secondly, being a two handed tank; it makes for a better linkup; skill wise, also makes more sense. Yes I know this would mean they didn't get Provoke; I believe DRK is going to have their own version comprised of darkness.
Arcanist though Black Mage makes sense I see ACN being the linkup over BLM simply because of some of the spells available in the ACN spellbook that are DRK from previous games: bio, miasma specifically. Thunder and scathe could also classify though which is why both make sense to me. Lore wise, BLM might actually be a bit ahead of ACN.

Machinist:
Archer is a given for me. I mean they're both ranged TP dps. Straight shot(as a cross class ability could be awesome), Hawk's eye, Raging strikes, Quelling strikes; great setup for cross classing.
Rogue is less given but what I think makes most sense. Being the only class that doesn't currently give abilities to any job, at least one of the three will use it and while Perfect Dodge makes sense on DRK; no other ability actually does. Perfect Dodge is a good dps CD for those oh crap moments, as any Rogue can tell you. Goad being a cross class skill, means it will have a better chance to be utilized in raids as if there isn't a rogue, it could still be present. Rogue currently doesn't list any other crossing skills however I could see Mutilate and Jugulate being cross class as they wouldn't have their modifiers.

Astrologian:
Scenario 1:
Conjurer is the default healing class, so it makes the most sense to have it be available as a cross class. Protect and Stoneskin are a must. Raise for early levels depending on when they get their own. Cleric Stance, because they'll have some dps capability.
Thaumaturge mostly because Swiftcast is too important to not have it as part of the lineup. However, as with the current classes that use THM, thats its only purpose.
Scenario 2:
In this thought process, I asked, what if they get their own versions of protect/stoneskin/swiftcast; which is potentially possible.
If that was the case, I started to think about what else could be crossed. Then I looked at it from more of a lore/mechanical standpoint...
Arcanist for Eye for an Eye and Virus. Ruin for a cheep spam-able dps would be useful too, depending on their dps spells. Throughout the Arcanist quests, they tell the player that you use equations and other such means to harness the Aether to weild its potential, which could easily be seen as a standing point for Astrologian.
Mechanist is a gadget class for what we can tell and would likely fall under the same type of category as Arcanist in smarts lorewise. Also, could give some CD usage or support ability to tie into the build of a healer nicely.
Scenario 2 is pretty much highly unlikely, but the possibilities it would create is interesting

With that part over, will any of the new classes share abilities with older jobs. Could in getting to 60, unlock DRK for WAR/PLD/DRG? MCN for BRD/ROG/MNK? AST for SCH/WHM? SMN seems outta place here lol

Thoughts?
