Played my first Hard Core character Lillith for all of 16 hours, made it to Nightmare level 36.
Kicked total !@#, had a great time.
Was disconnected from server and logged back in to find my HC character dead due to "Unknown".
Very disappointing, never again. At least until all the issues are worked out.

Post edit, my advice for others going the Monk route, Mantra of Evasion is where its at. Also a strong internet connection.
