Is there a hint of a future job according to this character (spoilers)?

[Zanarkand-Ronso]

Well,honestly, yes.before you get to heavenward you see Ast all over camp dragonbone so that was going to come evently.

Those are Astronomers, don't think they are a Hint at a Future job.

You see the Samuria in hw and the red mage so you knew that was coming.

Where? You can Argue Alisaie was the 1st red mage before SB dropped. But I dont recall any Samurai, especially in HW

We have dancers since reborn all over the place so you knew that was coming.

Your reaching if you think Scantly clad Miqote Dancing around is a Hint at a Dancer Job. By that logic we should have gotten them sooner.

Both Raubhaun and Griffon are blue mages so you knew they had to add blue mage.

They have not done ANYthing related to Blue Magic. But I do know that in XI there was a Bluemage under the name Raubauhn. And I think the Immortals or something like that was the group/faction name. Good references and nods to another game...but are not tied or hint to Blue Magic in XIV at all.
And his name is Illbert. :P

And you knew they had no choice but to add gunblades as a job because the entire imperial army basicly uses a gunbreaker

The Imperials do not use Gunbreakers. Gunbreaker is an art made by the Hrothgar (in XIV of course) which uses Aether/Magic Infused Cartridges on a Sword with a Chamber similar to a gun. The Imperials are using basically Swords with Gun Barrels on them. The Main difference is One can Cut and Stab and fire Bullets, the other Infuses the Blade with energy of some kind.
Just like Dancer, if there was a Hint this was coming, then we should have gotten it sooner.

Limsa basicly has a gunner guild (which sadly should have been added with duel pistols ... but they went with cids path of machines... which again is a hint.. I think the only one visually that never had a in game hint was Dark knight. But then again you can't have paladins without have their opposite be playable without pissing people off so dark knight honestly had to be added at some point so

What Guild are you referring to? Or at the least what did you see in game that looked like a Gunners Guild? And..I guess how is it a Hint at a future Job?
Because the "Gunners" that we got are Machinists. They literally work with Machines, and they Developed guns as another machine to help in ranged Combat in the Ishgard army.
I dont see a sinle point in the game that this is hinted at.
And...I dont think people would be in an uproar if we had Paladin and not Dark Knight. People would just be more mad if we didnt have another Tank Job to play, and it could have been anything other then dark knight. Heck, we could have Gotten that job THIS expansion instead of HW.

so Honestly they have no choice but to add a hammer job at this point consindering how many characters outside Gaia has hammers visually being used diffently than a warrior fights..

And honestly adding Geomancer now is a must consinder the amount of tease the game does and the lack of a job that honestly focuses on all the elements.

They could just make Hammer Weapon designs for the Tank Jobs. XD
And nah on Geomancer, give us Chemist. It would be alot more interesting to have a 4th Healer, and Non-Magical Healer at that. Plus it would fit very well if we are going into Garlemald since they can't use Magic.
Btw...did you forget Conjurer & Whitemages use the Elements?
