I've seen references to the Sherman having gyro stabilizers, which kind of surprises me as the M4 was intended and designed for infantry fire support; and not as a tank destroyer like the M10 Wolverine or M18 Hellcat or a heavier tank like the M26 Pershing which were expected to engage other tanks.
Of course, a 1940's gyro stabilizer is not going to be rock steady like a modern one, and the terrain is not nearly as roughly modeled in the game as it would appear in real life, so as a designed feature in a WWII AIR combat simulator, it's a wash.
IOW: if you modeled the gyro stabilizer, you'd have to model more accurate terrain, to include things like slick muddy surfaces.
Tiger definitely no longer the king of the battlefield. Still useful at long range and on the run, but if sitting still, and closer into the Shermans, it's often going to lose. Vs enemy aircraft, it still tends to hold it's own well.
