Like how brits "give up" double lmg upgrades, mortar pit, t0 lv, cheap healing on the fucking field and a non-doc puma?
Brits need to tech for nades and weapon upgrades. They also dont have a mobile indirect fire unit. They also dont have snares. They also lack capping power in 1v1. So I dont think the comparison is really all that relevant. Brits are a bad design as is but that doesnt mean they dont have weaknesses.
5 man Grenadier squads would make Ostheer totally OP.
As I said Ostheer isnt even underpowered right now (especially compared to OKW).
