I guess just a general question - do you intend to continue support for this addon with the new talent system moving into 10.0?

Am I missing a dependency? I downloaded the herorotation shadowlands branch as well as the dbc/lib shadowlands branches and copied the files into my beta addon folder.

I have no idea what's in your hero-lib-dragonflight and hero-dbc-dragonflight folders, but that's not the proper file structure.

Yes. We've already created a dragonflight branch, which is functioning on beta (and should function on the PTR).

Note: APLs haven't been updated, just core functionality.
