And yet the balance between US and Wehr was quite good. I am not saying we need to be like vcoh, just making an illustration/comparison. I agree we need to make USA stronger late game, the thing is that if we are good to huff their late game then we need to lower their early game because they are advantage there.
It is why you don't really need to make them stronger but add a cost to Axis late game survivability. Because all the game mechanics are made to give a 50% chance to Axis to survive early game and go late game. But late game, we aren't anymore to a 50% chance of winning for USF.
If Axis manage to survive early game, USF should also have 50% chance to overcome Axis late units.
The ideal would be to have 4 phases instead of 3 in the typical party. So each phase dominated by a faction is timed: 10-15 minutes early game, it should be also 10-15 minutes late game and next a last phase untimed where both side have equal chance to win the game.
Early: Dominance USF
Mid: 50/50
Late: Dommiance Axis
Ultra-late: 50/50
