I've said it once and I'll say it again. At the moment SE is playing catchup with the old system, the limitations that were introduced at 50 and 75 strengthened jobs like MNK but adversely hurt jobs like RNG and RDM. Now there are two ways to go about fixing said issues

1. Go back and adjust the current limitations. Including but not limited too readjusting formulas, accessability to gear that jobs were exempt from (for fear of overpowering), and tweaking job traits/abilities for balance.

or

2. Add more stuff and hope it fixes the problem and not create new ones.

I can understand SE's apprehension at trying to totally "fix" a job. The game can totally change again from 90-99 and the power balance can shift again, at the same time some jobs were hardly given any attention to begin with and are still awaiting that face lift.
