Lie or not Diablo 3 Hardcore isn't as nearly as challenging as Diablo 2. What David Brevik fought so hard to keep in Diablo series is just a gimmick in Diablo 3.
There's no thrill at all. Feels like you have to grind your way up to higher Torment tiers and the only thing you need is time. And that time isn't any more than grinding a SC character.
They could remove hardcore mode altogether now, I don't think it'd be missed much (even though all my characters are hardcore)
