Ravenscale drops
 

Question: will Ravenscale drop in CT on launch, or does that swap in post-Rubicite?

Ravenscale replaces Rubicite in the drop tables in Cazic Thule. That should answer your question sufficiently well.

I'd resort to the compendium of historical events within the Erudian Library, but it is widely known that Rubicite was replaced by Ravenscale.
