Well- I am getting random crashing with Diablo III. I will ask our resident IT guy to look at the situation, but he is going to swear up and down that it is Blizzard's problem- and not the networks. I thought I was getting random disconnects because he was playing League of Legends at the same time. It's almost 1 in the morning and his machine is shut off. I am still getting random disconnects.
Diablo III should have been a single player experience- not an online DRM one.
