I'm pretty sure the entire Square-Enix office is just standing around sucking their thumbs, I mean clearly they aren't doing anything, and clearly they're losing so much money they must be lazy.

They have to -reprogram- core systems in the game. They have to fix their formulas, algorithms, etc. They have several teams working on their respective content, some are translating, some are designing new art, some are writing stories, etc. Unfortunately in the world of game development we don't get hourly twitter feeds straight from each individual member of the dev team. I'm sure they are already working way ahead of "battle redesign" in other departments, but unfortunately the community (us) gets stuck behind the bottleneck at the programming team. Could they be short on staff? Sure. But the game is free, be patient or play something else.
