What you are saying is this: I want to drive, but I can't tolerate the risks involved. Instead of accepting the potential risk that everybody else does while being responsible for how, when, and where I drive to help mitigate the risk, I demand the government to protect me 100% of the time.
It's called !@#$ happens, m'friend. If you can't deal with that notion, then perhaps hardcore is not your bag. If Blizzard were to implement a fail-safe so characters immediately unplug upon disconnection, then people would abuse the hell out of it by pausing their games and unhooking their internet line. This happened a lot in D2 and it would be an even greater detriment to the hardcore economy since it would result in far less deaths.
If you want to get into the online-only aspect, well, take that up with Blizzard considering they're the ones who made a single player MMO game. If your connection is pretty shaky or your ISP is sketchy, then it's probably best to avoid hardcore. Kind of like how you shouldn't drive on the beltway if your vehicle is not road worthy or you don't trust the whims of chance.
Cars, if you're a good driver, you can always avoid something bad. You can even avoid some drunk nut job who comes out of nowhere, if you have good reflexes and are constantly aware of your surroundings. You can always lay some blame to yourself if you get hurt driving.
You're making a false analogy here. It breaks down because there is nothing in driving that is analogous to disconnect deaths in HC.
Anyway, maybe you and the other guy are right, and it's intended design that you should be expecting DC deaths in Hardcore. But we don't know
if that's the case. That's why I want this to be addressed. I want to see what the devs think about this. Maybe they agree with you, but we won't know until they say something.
Also, let me remind everyone that Hardcore is fun
! It is a !@#$ load more fun than Softcore. So even if DC deaths are intended in design, maybe they should reconsider. Maybe the longevity of this game can hinge on them making the most fun part of D3 more accessible to people. Nobody in HC is complaining about drops, monster difficulty, class balance, etc. Because HC is just making them enjoy the game a hell of a lot more.
As of the end of the seventh page of this poll:http://us.battle.net/d3/en/forum/topic/6794230367
The tally goes that 63 people are not playing HC because of lag/DC deaths, and 32 people are not playing for other reasons (although a lot of them did
list lag deaths, but it wasn't the primary factor of their decision).
