I’m working through the implementation of all the shadowlands stuff in the simulator. We have a thread going with progress updates:
I’m working on death knights right now and I might do druids next, so you’ll be able to play around with the covenants in the simulator very soon.
Kindred Spirits is going to be a little tough to simulate… we’ll have to make some assumptions, but I’ll come up with something and then we can adjust it as needed based on what we see happen in-game.
