Job balancing?

[Jin_Uzuki]

There just needs to be some sort of balance. Every job should be useful there can be preference but it shouldn't be set in stone. You should be able to take any job with you and be completely fine.

This will never happen. There was literally never a time in FFXI history in which "every job was useful".

The more complex your job system is, the harder is to have a proper ballance. And FFXI job system is very complex.

This said, there are some puzzling choices like the ability of SCH to self-SCH, but at this point what you can do. It's not like they can remove it.
