The current system is nice but need a lot of work to make it better. i have thought about it and i came up with an interesting concept. i built it upon the current system and what the devs said they want to do( specifically reverting the class names to "classic FF names").
the first thing is the physical lvl. it serves no point at the moment. to fix this i think adding a PL requirement to weps, this would be the recommended lvl alredy on the wep or 10 lvls below it, the devs have said they are thinking of doing this XD. another thing is making attribute points work proper, And finaly at PL 50 there is an unlock quest, this quest should unlock the other classes "unlock" quests.
Instead of reverting the names of classes to the classic ones i think we should keep the ones we have now as a base class list. At lvl 30 for all the classes there will be a "unlock" quest (this quest unlocks the potential of the class)(lvl 50 PL quest required before you can do these quests) that allow you to progress into a more specialized class.
for example, doing the lvl 30 pug unlock quest will alow you to play as ether a monk or theif, this brings back the classic names without changing everything to do with puglist. another example of more advanced unlocking would be pally. too unlock you need to do the GLA and CONJ unlock quests and then a final you can do the Pally quest to play the pally.
And beyond the specialized classes you can go further. lvl 30 black mage unlock quest and the red mage unlock quest done you could then do a blue mage class quest
or maby White mage + Red mage to do the summoner quest
This adds tons more content to the game in the form of quests, many many quests, and different weapon and armor sets. and allot of story for each class and its development.
here would be a basic breakdown. it could get much much more complex
(spelling is bad sry)
GLA---> Knight
GLA+CONJ---> pally
GLA+THRG---> Dark knight
MRD---> 2handed sword/ax user( dont know the proper name)
Mrd+PUG--->corsair
Pug---->monk
Pug---->theif
Lancer--->Dragoon
Lancer+GLA----> fencer
Ranger--->archer
CONJ--->white mage
CONJ--->Black Mage
Conj---->Red mage
Thrg--->scholar
THRG--->Blood mage(thrg has blood magic seems like a natural transition)
