To me, the only appeal of HC is that for those of us who aren’t overpowered, fate favored super beings, our deaths come early on as most anything bigger than a house cat can probably kill us without a lot of trouble.
It’s like that scene in BFA where Anduin is watching all the coffins being unloaded at the docks – it’s the fate of the vast majority of us who go out adventuring. Or like all those trails in Tanaris that lead to broken wagons and bones; that’s how most of us would end in Azeroth reality.
