Cross class skills and traits

[Nurvus]

We need more dynamic interactions between existing abilities so that our rotations become less predictable, and offer more opportunities for skilled players to stand out amidst the rest.
That's the only kind of Traits I hope they add next.

I speak mainly of procs/stacks generated through "controled RNG" (i.e.: 100% chance on crits with specific abilities. or X% chance from abilities regardless of crits, X% on tick from ability Y to reset cooldown of ability Z) that provide an opportunity that involves meaningful decision-making in the middle of combat.
I'm not talking about PGL/MNK-style buff maintenance.

Because right now, there's very little room to distinguish two players with the same gear and Job - assuming both know the enemy/encounter/Job.
