They can't do magic bursts or skill chains because much of the combat system is still from 1.23.
I want XIVs take on Skillchains and Magic Bursts.
I think everyone who played FF11 will say skill chain and the magic burst.
This is the crucial element of FF11 that FF14 is missing.
More party areas and levels with the addition of fields of valor. This may not be what the vast majority of players want, but I do believe there is an audience for it.

If its just in Eureka I think it *might* be possible, SE sometimes surprises us with what they can do. Another option that might be cool is Limit Break skillchains, or maybe add a small chance if 2 or more parties uses the Limit Break at the same time when the target is under 20%HP could trigger an Active Time Maneuver that finishes it.
They could put the adrenaline rush system in Eureka, and create skill chains between them depending on the jobs, especially considering your rush could have an elemental affinity thanks to your wheel.
This would also shift the meta away from "everybody goes RDM" if other casters bring a Rush that bursts better with the other jobs in the party.
It would also give more depth to the wheel as you'd want to shift if for how you'll open the skillchain, to ensure that the hypohethic magic burst targets the proper elemental weakness.
Sigh, I miss the day when Eureka was base on FF3
