RDM Zodiac?

[Esp]

I think you need only Stormblood for the lv61-70 jobquests. Heavensward will give you the lv51-60 jobquests.
Without Heavensward and Stormblood the RDM will be already at max. level (level 50)

I am not completely sure myself, but "Unlock RDM job" is plastered all over the product information for Stormblood, so it's why I figured even though it is in the old 2.0 area's, a Stormblood access key would probably still be required to get RDM.

For me, it's part of their selling point of the expansion.
