Blizzard Confident in Diablo IV Launch Servers Despite Missing Features

Blizzard is "really confident" that the launch of Diablo IV will not suffer from server issues that plagued the launch of Diablo III. The team spent over a year testing the servers with automated bots performing simple in-game tasks and found valuable data from real players logging in during beta tests. The game requires even solo players to log in to the game's persistent servers to play. The recent "Server Slam" beta test featured servers that didn't seem especially slammed and very few reports of long queue times or login problems.
