Why we cannot play with joystick on PC?

Why we cannot play with joystick on PC? Setting up the mouse with quick keys is nice, but with a joystick it would give us more freedom to play like console version. Shouldn’t that be an option?

Traduzindo para português: não é possível jogar Diablo 3 para pc com joystick.

No, Diablo 3 doesn’t have this option. It’ll be implemented in Diablo 4, only.
