I think it would be pretty neat to add "Band" Abilities to this game. Seems pretty bland that its just Braver/Bladedance/Final Heaven for DD limit breaks.

For anyone who doesnt know what band abilities are, they were introduced in ffIV: the after years. Basically its like a team based limit break where 2 or more people were incorporated into the attack. Example, if 2 dragoons are in the party instead of getting Final Heaven it would be a different ability specific to 2 drg being in the party. Since I dont foresee these people adding in Skillchains or Magic bursts from ffxi I think it would be a pretty nice way to put more emphasis on your specific teams jobs, instead of lets bring only X job because its the only DD worth bringing ect.

And as they add new classes/if they add new classes the system would be able to keep expanding due to the number of possible job combinations that would be able to exist in a party
