Lets think about the class system/Amoury system...

[Zantetsuken]

The OP has some good ideas, but I don't think we will see any changes.

Keep in mind that the current Japanese names for each class are directly tied to the Armory system and are named specifically after what weapon/tool is used:

Marauder = 斧術士 (Axe Master)
Lancer = 槍術士 (Spear Master)
etc.

And since the Armory system is here to stay, we won't see multiple types of weapons for each class (at least not radically different)

However, the relic system shows us that jobs can have different weapons than their respective classes (they auto-equip the job soul needed ).

So DRK could be another job for MRD but have access to Greatswords or Scythes where MRD (and WAR) wouldn't*

*just an example.. I don't want to start an argument over what class DRK should come from.

If you guys didn't read What Zant said:

So unless the Japanese names for the classes change to match what we get in our English I Don't see multiple weapons for each class.
For those that keep saying classes are useless Post 30, I beg to differ here. Classes vs. Jobs post 30 all depends on what you are doing and the Class itself. GLD to PLD is obviously a better choice as nothing is really lost for solo or party play. But then look at the magic Classes over the magic Jobs the classes are usually better for solo as you not limiting to a group of mobs weak to either wind or thunder or earth is you don't mind the recasts. Plus with BLM your only healing ability is Second Wind, not nearly enough in dire situations is Sleepga failed or was interrupted. But as this was all for 1.x, so how we utilize a class vs job will be different.
My only gripe atm from 1.x point of view is the 2 sub classes that some jobs had, mostly the magic classes here. WHM was gld and pgl while BLM was arc and pgl. WHM's subs where ok as gld has some decent abilities to make whm survive big attacks with sentinel. But blm's arc and pgl has access to only 6 abilities with 2 being silly on blm and another useless.
that's 3/5 abilities set if you did the math. I hope the reworked armory system removes pgl from blm subs and gives it cnj and the same for whm; pgl to thm.
Now to just wait and hope to get into the beta to actually see the changes the SE team will make. Even if I don't like particular changes to the classes or jobs, as long as the game plays well and I enjoy it, there is no reason I "have" to play on the classes I don't like.

This person knows what's up. Most people here have this conception that Jobs deviating from a Class HAVE to use that type of weapon.

It really doesn't matter that classes are here to stay. Time will tell to show the new revamps that the Battle Team has planned.
