Very cautiously... though my poor hc chars always seem to die for very silly reasons. Had so many lag deaths/DC deaths when the game first came out. I gave up for ages, then tried again, got a monk to level 18, didn't play for ages... went back to visit her after the recent big patch, and she'd been put on expert difficulty. Game wouldn't let me change it. I went out to see if I could possibly survive, found one bunch of blue dudes who took half my health in one hit, so I ran away and left the game. Went back in later and she was dead :'(
HC chars can't change the difficulty of the game while you're in it. Gotta exit back to the character screen first.
On a side note, wooooo! Managed to get to 57 before beating Diablo on Expert Difficulty, then I dropped down to Normal mode to do the Act 1 speed run achievement. Got 60 along the way. Now I'm Paragon 10!
