You want to remove OKW's trucks, and you think the reduced income isn't a disadvantage.
Okay
And the thing with Bunker and FP spam isn't that you can move one AT gun up and clear it, it's that you have multiple Bunkers and FP's all covering each other so you can't flank them while Rifles + rear's in the FP's can deal with any AT gun pushes.
Shutting down territory with defenses is part of the game, it's never not been part of the game. At this point it's stupid to argue being able to stop the capping of cut offs and fuel somehow makes things unfair when every faction is capable of it.
Lower income but cheaper tech and more powerful units. It's not lower income - nothing, it's lower income - best tech and best units.
I have 1400h with CoH2 and I saw bunkers, a saw sometimes 2 bunkers, but Ive never ever seen something what you are describing.
Wires, sandbags, flak emplacement, bunkers, mines - this is defense. It requires micro, tactic and planning.
Schwerer has nothing to do with those things.
