What makes Darksun problematic beyond slavery existing and being a bad thing?
Also what else would Defiler, Preserver, and Sorcerer-King Patron be used for?
I did a few Spelljammer conflicts they were fun enough. It would have been nice for there to be more upgrades, but it did it’s job.
Once again I view it’s big flaw as it’s length it should have been longer.
Planescape alleviates those concerns by being longer and better.
