Hello There, I'm an insanedifficulty.com old member,
I don't know exactly what happened with that site, heard there where some problems with those managing the site.
Anyway.
I was looking for those BIG pictures in the FAQ: https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcScOMAR0a8drUgxYn4bPs_XkDWjodXGMXfmS4aMYvzHZPAvnsD6
Containing tables with all the skills and formulas for every Job, Special Job, Item, Enemy, etc. in the game.
I also wanted to know how much people is around interested in 1.3 so a dedicated Forum section can be made for us if insanedifficulty is not going to revive,
That's all, Thank you!.
