A RDM Equivalent to BLM Triplecast

[Archwizard]

I don't get the point?
Unless you want to rework RDM's rotation, which is another topic in its own right.
BLM's triple cast is a utility tool, because movement is much more "dangerous" DPS wise than it is for RDM (or SMN).

I'd argue that Triplecast is also a small DPS boost, since more than one spell in BLM's arsenal has a longer cast time than its GCD, and even one second faster cast time can mean the difference in losing a Polyglot charge.

But I agree, RDM has a lower value of necessity for additional tools to render spells instant for movement phases. Non-zero value, still higher value to RDM than SMN, but significantly less than BLM.
