We all know about the coming battle/job/class overhaul that is coming, but does having jobs to find class uniqueness is really something that should be worth to discard our customizable options of the actual model of the armory system.

So i suggest this model that follows to certain extend FF Tactics and FFXI

Tree of Skills, yes this may be seem on several other MMOs and many dont like them but.

We could have Tree Skills for each Job and for each Weapon.
Also make that the attributes be worth something and share points used to get skill too
Since I pointed the basic idea ill do an somewhat detailed example using classes
Black Mage, Gladiator and Culinarian

So lets start with what kind of allocate system would we use. I say something like FFX
lets call them AP /not ability points Aetherite points/. You would need a certain amount of EXP to earn one or several points

With this lets say that we have access to basic classes/jobs those being the actual armory system and lets say the 6 basic jobs from FFXI

So lets start with the attributes section to maintain the balance of the game we should be allowed to add just a certain amount of points in general.
The actual threshold in the system work nice that after you add certain number you would need more points to increases the attribute

Lets go to a Black Mage now, we have all basic magic fire/water/stone/aero/thunder/blizzard, each magic should have a small attribute requirement for example all these basic magic should have something like 12 INT 5 MND basic requirement to obtain. Now each spell should have tiers like we have right now tier one should have the stat mod like 100% INT+ 100% Elemental attribute the next tier should increase the mod to 120% until certain cap.
Now to continue getting along the path lets say we want to learn Fira again certain requirements should be met on the attribute section but you would need Fire II in order to learn.
This can be done for all spells in all elemental families Blizzard/Blizzara/Blizzaga/Freeze
with the elemental DoT at a somewhat similar degree.
Job Traits should come along the same road but the requirements should be harder since they should add nice bonus. Job abilities too only after learning certain number of spells and some job traits you should be able to learn them and just like merits in FFXI and the tiers in the spells making them stronger or lower the recast in them.

Now lets talk about the actual classes we have.
Gladiator /Sword User or Practitioner/ That should be the actual introduction from the Japanese name but since our localization is odd like always it lead to a lot of mistakes.
So i will call it the Sword Skill Tree, in FFXI we had this and after certain leves of mastery we would get skills, I belive something along that path

Just Like Black Mage each skill should have certain requirements in the attribute area and that we could have certain Weapon Traits to learn in this case if we use a Sword after learning this Trait we should have the bonus only if we use a Sword and not if we use other kind of weapon. This should have some affinity to them too let say certain Weapon Traits Get additional effects or bonuses when you pair them with other Job Traits something similar to the Passive Traits you got mixing spells with Blue Mage.
So what jobs use Sword Warrior/Paladin/Blue Mage you can guess that sort of mix

Now for the crafting area Culinarian in this example.
You should add Ranks lets say this you learn Amateur this should have you learn some basic Class Traits just like those you learn with Guild Marks but on a more varied tone
You wanna learn to cook something from certain family of products you have to learn it and after each rank Amateur/Aprentice/Veteran/Craftman (for example) you get better tier of those Traits witch make you more proficient cooking that

Now many people would complete disagree to me since they would think all the work they done would be for nothing getting those 3-4 classes to 50. Well why not make all that SP into points to allocate how you see fit.

I Think this way they can add the new jobs /even advanced jobs/ without making us stick to a role allowing us to make our character however we want them to be. But Like we know being unique doesn't meant you are useful this could make us decided on certain roles and maybe making them stronger from other classes like how the armory system was intended to work. Also AP should be in a certain way available to obtain but each time you get the next would need more EXP making this something more goal-oriented leveling since we want to get AP to get new skills/abilities/traits to become stronger.

This like the tittle says is a suggestion I would like opinions on if this could work and why it could not work. Also Please if you will just troll...meh why do I care there is always one
