Ostheer went downhill since the Brits arrived.
No other faction gets punished as severely as Ostheer for making a mistake due to the four men squads. The fragility of Ostheer early game is intended. Or to be more specific: It used to be intended. Ostheer could compensate with its lategame advantage for the lack of good early game. Brits destroyed this concept of lategame advantage, the additional tier that was until then exclusive to Ostheer. And even USF and Soviets were buffed in their lategame performance.
Nowadays Ostheer struggles through the early game and tries to perform against overwhelming odds only to find itself in a mediocre lategame. There is no light at the end of the tunnel so to say. No compensation for your fragile units, no reward for staying ingame. Sure, there were some buffs to Ostheer early game but none compensated the four men squads and punishment for even the slightest mistakes.
But a good German lategame is seen as blasphemy by many and thus we are here now wondering why Ostheer is neutered. The least that could be done would be a 5man upgrade like the Brits have since mirroring the factions seems to be a thing now.
wow finally someone
