questions that would need to be answered if someone were to make a character:
what level do they start out at?
campaign setting?
what skills are there?
what exactly does dex do?
is there a constitution?
are there saves? and if so what makes them apply?
how do you get your +to hit?
what weapons are in this setting?
how much are spells and what spells are allowed in this campaign
what is concidered 'pre-battle'? or is it just on the rogue's 1st attack?
how does a pirate's skill work? is it just hey, i want that boat, i use my skill, i now have it?
what is a cleric's key attribute?
are there abilities you achieve past 5th level?
how exactly does sue work? you throw money at them?
does your defence get re-set each level?
who can wear armour who cannot? and with this system how is it affected?
how does your mana system work? like a chart for the mana cost would be great

if i understand this correct, you are trying to make a final fantasy 'd&d'
saying that i believe would help alot.

balance point of view:
from what i can tell, sorcerer's can do just as much physical damage as a fighter?

and if i get this right, 'defence' is just extra hp you have


that's enough questions for now
