I agree with Ciez, but the problem is the allied armor is limited...in terms of use. We have some broken ability/imbalances here and there.
Allies cannot utilise their armor as much as the axis due to the strong axis AT on the field (which can be only dominated by arty or/and spam --> not reliable in 1v1). This has a huge impact on late-game, but mostly the USF suffers from it because of their fragile tanks while the soviets can compensate this with call-in units (Is-2, 85s, marked target).
Ever tried to kill a Tiger (don't forget blitz) with M36s when it has double PAKs and vet 3 lmg gren support behind it?? Even P-47s do shit against it.
Or PAK-43 or AT + german armor in late-game? It's not the panzers that counter your tanks, it's the AT protecting the axis tanks from your tanks...which is way too effective against the allies
I'd go for fixing the call-ins first and fixing the axis AT so it wouldn't deny allied armor.
