Diablo 3 won’t be getting controller support on the PC, but the reasoning behind Blizzards greed makes perfect sense.
“If I let you use the controller on the PC, then I have to let you use the user interface that goes with it, and if I give you the roll and I haven’t throttled the number of enemies attacking you because the mouse-and-keyboard players can handle all those enemies, but with a controller you have too many guys,” Berger added.
When you think about it one of the things that Diablo players loved about the series and wanted to see more of in Diablo 3 is frantic widespread battles with dozens of enemies. Slowing that down for PC players would likely be a step in the wrong direction that the loyal original fans of the series might find insulting.
Less is sometimes more, and in this case no controller support for PC might be a seriously good decision.
