There are situations were the old scott would get lucky hits and completely destroy full health axis squads
Yeah, even a P4 will do this to full HP allied squads. I think situations like these (with vehicles that aren't meant to be as destructive or wiping instantly) are unintentional and just a result of the implementation of mechanics of cover and individual model pathing especially around objects.
I appreciate your reminder that the Axis have many tools to deal with Scotts which are nowhere near as devastating as tier 4 brumbär/pwerfer or stuka zu fuß.
