Not at all. Fungal and Crystal are definitely not discord exclusive dungeons and neither are Lost Halls cult runs. Deca also plans to implement the exponential HP scaling across the entire game anyway so I feel that public void runs will become a definite possibility once that has happened.
I just want the difficulty of Shatters to match the lore description. It’s supposed to be a terrifying fallen kingdom, but right now it’s kind of a massive pushover.
