Shotgun is ezmode on console for the same reason Martini Henry is ezmode on console, the high risk high reward isnt truly any high risk when a computer makes sure u dont ever miss as long as ur crosshair is semi close to the target.
Only when targets are further away and u need to lead them u may miss with auto rotation, but never in Shotgun or Henry OHK range
With auto rotation off and its a different story, guns are way better balanced then with the exception of the Hellriegel laser
