I think the current option allowing dead Hardcore characters to cross over to the normal PvE realm by walking to the Dark Portal is unintentionally weakening the Hardcore realm’s long-term population.
I know we have low numbers overall already, but hear me out.
Right now, a couple days after mass signups have been enabled, it is already very difficult to form groups for low-level dungeons on the HC realm.
At the time of writing, based on the community Discord’s #system-hc channel, I have seen 1,554 recorded Hardcore deaths, many of them at very low levels, including a large number under level 5. Meanwhile, 234 characters have crossed over, mostly level 10 and above. There are currently around 140 players online.
The concern is that the transfer option changes the psychology of the mode. Instead of committing to the Hardcore realm as its own ecosystem, many players will treat their HC character as a “one and done” attempt, knowing that if they die they can continue playing that same character on a fresh, recently launched PvE realm.
This risks slowly draining the HC realm of players who might otherwise reroll, rejoin the leveling pool, and keep dungeons and grouping alive. Hardcore depends heavily on population recycling - dead characters normally become new characters, and this keeps zones and dungeons at all levels, active. If too many of those deaths instead become transfers, the HC realm can stagnate very quickly, especially when we're already starting at low numbers.
A healthier compromise would be to restrict this option to level 60 characters only. This would allow players who finish their Hardcore journey, or who want to continue after dying in Inferno-style endgame play, to preserve their character afterward. This way it would function more like a post-mortem Hardcore deactivation, similarly to TurtleWoW.
Alternatively, disable crossover and reactivate it later as it is, only once the PvE realm is more established and the HC realm has had more time to stabilize its own population.
