You have failed as a player and should uninstall if you actually allowed any kind of med to hit rear of your panther without literally pushing it alone to allies base sectors.
Why so many players here struggle with the concept that units that are being microe'd perform better then ones that aren't and its not a balance issue?
My point is that:
USF where designed to be about decision making do I want support weapons or light vehicles?
Soviet where about decision making, do I want tank or TD do I want infatry or support weapons?
UKF still have some choices that are being removed like do I build an AEC or bofors?
These decision making has been slowly been removed in the new environment it is seems "inevitable" or "necessary evil" for OKW to also have less impactful decision making.
Because in practice it does not work and to work results in the need of having units that punch above their weight to justify limitations.
Especially if that "decision making" results in dead tier or multiple tiers as a result, as it was with soviets and USF.
Panther can park so close it will literally insert its gun into T34s turret and will win without a sweat.
None of the allied TDs can do the same to P4.
