If you could adopt and adapt a system from any FF title...

The FF9 gear ability system is what I was anticipating or FFTA style. Learning abilities from gear. Wearing the same type of gear allows those abilities to stack up.

i.e. White Mage staff allowed you to use White Mage abilities. Robes improve caster stats via learned traits. Switching to other robes allows you to maintain robe traits. Switching to heavy armor, you might not benefit from robe traits.

At least in terms of a leveless, Armoury-driven system.

I bet XIII's battle system could be implemented into an MMO somehow.

and Yeah, XII is the most feasible, seeing as how it is basically XI, but you can control your party o.o

I think if the old FF14 stamina system had been reworked some, it would have functioned closer to XIII's battle system. I think the chain, stagger, and wound mechanics would have added pretty in-depth, quick paced combat on top of incapacitation.

iirc, Chocobo companions were going to use something similar to the gambit system. I remember reading a rep post about that somewhere.

I wish they could adapt Monk battle system from FF6 like Sabin chara, where we can switch between traditional skill menu selection or using movement keys ala Street Fighter 2. That would be awesome!

I 10000% agree with Blitzball or something similar! Was very epic.

I also miss "boards" for stats and stuff, i wish we had a board for stats and skills rather than lists =( idk what it is but i just feel a sense of progression and enjoyment went going through the board on ff13 or ff10, ff12's got me a little confused because it was tied into gear but it was super sexi.

FFXII Rare game board, FFXI Nyzul, Sea and sky type of content ,open world content plz.
FFXI blu, gambits for NPC only, cuz if they ever make us have one, their AI will be ....
Limit Breaks, something that can make a diff, not the 15min crap we have.

Card Game.

If not that then the conquest system from XI. It would at the very least help form a sense of national pride for each city that is severely LACKING in this game.

why no one's interested with Sabin's Monk abilities...
It would be fun playing Monk ala Street Fighter.
