Think of it as faction flavor.
OKW has vet 4 & 5.
USF has vehicle crews & weapon racks.
Soviets have 6 men squads.
Brits have their green cover bonus & weapon racks.
Ostheer has... good team weapons & tanks?
It's not wise to remove content.
Resource penalty was indeed an essential part of that flavour, and when u remove one flavour the remaining makes the faction imbalanced. U can't simply just remove that very important flavour and expect the rest stays balanced, even though I think this change is in a good direction, BUT ONLY IF THE T4 ACCESSIBILTY OR TANKS GET INCREASED PRICE BY A LOT.
My favourite faction of choice have always been OKW and I played 3000 hrs of this game solely OKW, so I'm not a fanboy or such or anti-OKW, I just like the game to be balanced!!!
