There was recent concerns that Asian servers of Diablo 3, located for Korea to take advantage of its comparatively well established Internet infrastructure, were congested. Some South Korean gamers petitioned Blizzard to ban non-Korea IPs from access Asian (Korean) servers. What the Hell?! Those are Asian servers supposedly serving Asian versions of Diablo 3, including Chinese versions.

More worrying fact is that Blizzard may lean on Korean gamers. Starcraft simply is dominated by South Korean gamers. And Blizzard, please be responsible. You are selling all those copies, then without doubt you are responsible for maintain server operation for every single copy of Diablo 3 you sold.
