Autopilot is a constant in my life...
I'ts like talking to my lawyer...
But in MB, I enter autopilot mode when I can't do exactly what I want (some timing, for example). Then you just watch the screen meanwhile your character makes its own fight. Sometimes you get pretty good stuff, so I've started to save those fights to study them later.
As I started to play MB seriously, the autopilot is less frecuent. I wish I could enter that state on purpose.
