I now have several hundred hours in hc and have not died to lag once.
Well I have hundreds of hours in Softcore and have died in the double digits due to lag. Don't get me wrong, Ive died sooooooo many times from either doing things I shouldn't have, playing stupid, or just goofing around; but that doesn't take away from the fact Ive had disconnects kill my characters.
There's nothing wrong with preferring HC over SC, but there is something wrong with thinking that everyone else should feel the same way you do.
With Comcast as an ISP its tough to hard core. If there was an offline mode, I'd rock it. I got to like Paragon 60 in HC last season, and forgot to get a character to HC70 this season so I didnt get the last season reward.
Having separate HC milestones means you have to play 2 characters a season; not something a lot of people want to do.
