I'm new and i haven't bought the game yet. I was looking at walkthroughs and other things for these answers and couldn't find them.
1) When you change jobs, does each job have its own Job Level (like FFXI)? If not, how does changing jobs work?
2) When you learn an ability for one job (like Curaga with White Mage) do you keep it? Can you use it if you switch to Ninja or another job?
3) Are there sub- or secondary-jobs?
4) Can you make your own character?
