What isn't their to be worked on. After battle then you have tweaking it and more tweaking. Jobs and the jobs actions, then tweaking those x3 and the LAG dear god fix it. content, AH or tweak what we have now. New areas, Dungens we get in 1.18 so i guess tweaking those. Mob placement and tweaking the mobs HP,DEF and attacks. and so much more.

EVERYTHING in the game needs fixing. I would think get ride of the lag if they do that then the game will feel better and battle will be fine.
