It seems like noone seems to care that Diablo III has always online DRM so you can't even play singleplayer without being connected to the internet, let's say your internet is down or being really slow, it ruins your game experience. They could just turn off the quickjoin feature.
In most other games people think it's all out unacceptable for this kind of DRM but most people don't seem to care about Diablo.
Now, I just want to add that I love the game and that I usually have a stable internet connection and I'm mostly looking for opinions on this subject. But the rare circumstances that my internet is offline it would be annoying not to be able to play.
