Sure, if it's released with those bugs I won't buy it. But it's in beta, and from what I read just now, those are blatant bugs. Or do you really think a company that prides itself on releasing pretty high quality product would suddenly let slip a game which loses player save data upon internet connection loss? Even wow doesn't lose your data if this happens, not unless they are having serious server issues which is once in a blue moon. Think about it.
As for an always on internet conn; shrug. I don't like it, but it does make sense. I imagine that one soon day all games will be like this, it does help reduce piracy* and give them a tight grip on hacking. Like I said, if they can make games like wow retain your stuff when you lose connection, then clearly they can do it for d3 and any other game. But I wouldn't expect it to be working in a beta, the whole point is for them to iron it out in beta.
tldr: Wait for release before moaning.
*Yes they can still hack games for solo play offline, but I suspect more and more features will require an online connection up to a point where pirated games are cut down versions of games.
