The potential for unit power is more relevent the later the game goes. Munitions matter far less the later the game goes, and generally get dumped into 1-2 abilities like CAS. If the cost of the upgrades matters, T34s should be receiving a nerf to their MGs since their hull MGs deal equal DPS to that of the 3 MGs on the p4s, except P4s are required to pay for it.
Well, for that I'll pull up one of the favorite arguments around, "it's doctrinal".
I guess PZ4 understands how Assymetrical Balance works.
Your point is that this makes USF lategame even better vs OKW, who can struggle against them already, if they are allowed to get both fuel and munitions?
Because I can't deny the new doctrines are just BETTER than the old ones but there wasn't much competition to begin with. Pershing only meta remembers that.
