The entire Ostheer faction makes no bloody sense.
Bunch of tanks that either don't damage infantry at all (a StuG with a mounted MG can stand right in front of an infantry unit for half a minute and not take out a single model) or very little, thus needing to be supported by infantry at all times, and...
...bunch of infantry that is drastically less durable than any other faction in the game both on a per-squad and a per-model basis, thus unable to reliably support armor, especially in the mid-late game.
The Panther is just one of the many absurd symptoms of this, alongside the unarmored armored car, the impossible munitions expenses (either upgrade Grenadiers/Pioneers with weapons to have any chance in direct firefights against other factions' basic unupgraded infantry, let alone upgraded, or use grenades/mines, but not both), and the instawipes (now seemingly more or less fixed via the model spacing adjustment).
