Why does the IS-4M reload slower than the IS-3 although it has more space inside and a ready rack in the back of the turret? Considering it’s higher BR and the faster gameplay it should get at least the same if not a shorter reload to allow it to actually fight instead of having to wait half a minute to react when your gun which is mediocre at best fails to penetrate the heavier opponents that all have shorter reloads. To not make it too powerful it should only get lowered a bit to be roughly betwenn the IS-3 and the Jagdtiger reload time. That way it will reach the 3-4 RPM it had irl.
Suggestion:
Reload 27.0s - 20.8s → 25.0s - 18.5s
