Holy jesus. You guys are all too very used to having all Jobs in one Character.
Remember: Other games don't have that problem. And FF14 doesn't have it either.
If you want to make multiple raid runs in a week, or have a different cap for each class, just freakin' create a new character.
Even if you have to do all of the Story and shit again, you still have a whole different class, seperated from your other character.
The problem doesn't really exist, but YOU make it exist.
