A rework of the cross role system to have more situational yet impactful passives. But nothing mandatory (like, no lucid dream/esuna /protect).

These could include traits altering skill.
For instance, a trait would refresh esuna upon death / grant u 50% total mp when being rezzed.
Or one could be a healer self rez once a battle.

Basically, things that would be situational, so that you could adapt them to your current progression or party. But there shouldn't be any clear winner.

I would also like some job related way to specialize. Again, the choice should reflect player playstyle and shouldnt be obvious.
