How can they add more classes and make them unique and have their own flavor?

[Sandpark]

They have done it in FFXI with 22 jobs and have many more jobs to choose from in the FF universe. The question isn't can they make them diverse.
It is do they want to or is there a reason to?

Questions to ask yourself:

Why are multiple roles tied to one job needed?
A)Less unique defined job choices created.
B)Loose group based rules in open world content.
C)Loose group based rules in instanced content.
D)The possibility of one job being different from another player playing the same job.


Elaborations:
A)Do you think unique story will be created for seperate builds like heal, dps, or tank? Will it be as unique as starting a brand new job with an original background?
B)Most things are instanced and have strict group requirements for duty finder. WHat if dps entered duty finder with healing skills rather than dps boost.Is a DPS paladin hybrid really going to be better than a full DPS monk?
C)Is there a ton of open world party/solo based(not public)content in FFXIV where individual/multiple roles are needed on one character? There is little open world content besides fates,hunts, and diadem, monsters hp reset hp if you make them stray from preferred zones,monsters resist many things, jobs have long cooldowns when switching jobs to prevent OP, jobs are penalized for too much movement with skills.
D)What is more unique, one job being different from another player playing the same job or one job being different from players on other jobs.

My thoughts on making combat and future jobs/classes better:
1.Remove the GCD and have mp/tp/individual cooldowns be the resource.That makes the game more dynamic and flexible versus worrying about watching spinning circles rather than action on screen.
2.Introduce more classes and remove class cooldown on open world content so people might actually use them more outside duty finder or perhaps use in future solo/duo dungeons.
3.Remove class restrictions when playing a class. In other words, let classes mix and match from different classes as we see fit. Just make their base skills/traits the most potent.
4.Allow jobs to use class skills from any class they want but keep them limited to how many available at one time and this only applies to open world content not duty finder instances. This allows more flexibility and builds for jobs as it did in ffxi.
5.A deeper gambit system for pets and companions similar to FFXII so we can custom tuned how we want our companions/pets to react.
6.Bring back the path companion system so we can have companions more inline with what an offline FF entails. Characters with stories like Auron, we can bond with them.
7.Eliminate the invisible walls. If I can't jump in it, over it, or go under it don't even render it unless it is a background in the far distance.
8.Rework the materia system to enhance certain skills and not just attributes. And don't lock the materia to gear once melded, perhaps a book similar to a glamour book that let's us swap and use sets outside battle.
9.Rework guildleves to be a springboard to unique instanced contents like hamlet, besieged, BCNM,the possibilities are endless. When you activate a card you are instantly teleported to a content with other players inhabiting it, from there a player could choose to group or solo. Of course the type of content will have some limit to how many players can enter at once.
10.Please introduce some intelligent open world systems in the future.

Thank you.
