Hardcore and paragon 2.0???
The new Paragon system is very forgiving for Hardcore character death, and Paragon levels will be stored on the account rather than on a specific character. A max level character will earn Paragon experience for the account (which all of the characters on that account would benefit from), but if that character is deleted (or killed in Hardcore) all of the Paragon experience they gained remains on the account. It's still separated by Normal and Hardcore modes, though, so you're Normal mode Paragon levels won't benefit your Hardcore characters.
