I know that the primary purpose of Spirit Binders is to change the respawn point of PCs.
But that point is kind of rendered moot due to the main rule of Hardcore League.
Why are they still in the game?
Is it easier to leave them in the game than to remove them or write new lines of dialogue just for one server?
Admittedly, I can see one reason they're still in the game: Mummy Rot.
Since that's the bane of all PCs, that may justify them still being on the server.
There is also no reason for Siberys Spirit Cakes or res shrines to be on Hardcore League, as they do not save your life.
