There needs to be a discussion on using the occultist to reroll stats (enchanting). I have not done it yet in my runs as the only characters in sorftcore I have in T3 or above were ones I did runs for... BUT this is an absurdly strong advantage for any run prior to T3.
If it were to be approved, which I am not sure I would even be in favor for, I'd suggest that the only run you can do rerolls for is the fallen temple. Again, I am hesitant on that. I am really hoping there is some patch out there that adds the SSF realm or something where you get a clean character but in the meantime we probably actually need to have a few actual sit down - round table - rules discussions.
The thing I would want to avoid the most is for both the Diablo 4 at large and the speedrunning at large communities to call this whole thing a joke. Which it could quickly become without a lot of communication, explanations, and clarity as the game itself does not make this a simple answer.
