Admittedly, I find it funny how we even have elemental resistances if they do jack all. Why are they even taking up space in the character screen?

I don't see changes to how the elemental wheel (or lack of) works in this game because it would require a complete overhaul of Black Mage and most likely the other Disciples of Magic jobs. They would also have to redesign fights both old and new to take on such a change. As Winter said, its a lot of work for a system a lot of people might not even like and I too am not shutting down the idea, but just looking at it from a realistic standpoint.

Maybe in the far future if they ever decide to do a big redesign of the game like they did with 2.0, but not in 4.0 or any time soon.
