Would Sov be the allied benchmark then since both OKW and OST have around a 50% winrate?
It is far simpler to use one benchmark and not two. First one decides how strong Ostheer (as an example) need to be. Then one balances all allied faction vs Ostheer. Finally one balance OKW vs all allied factions.
Also I feel like if you fix Mobile Defense (which is happening next patch right?) OST will be very balanced.
Similarly I find SOV and OKW balanced well enough to not need sweeping adjustments. UKF and USF have issues hopefully fixed soon/eventually.
Well imo there some Commanders that are problematic have access to a combination of abilities that they should not have like powerful infantry weapon upgrades, super heavy tanks and powerful off map.
I will bring 2 as an example there others:
Jaeger Armor Doctrine
Combining Reconnaissance Overflight/Stuka Bombing Strike/Elefant Tank Destroyer. This combination should not be allowed.
Lightning War Doctrine
Combining Jaeger Light Infantry/Stuka Close Air Support/Tiger Tank This combination should not be allowed.
On their own this abilities might be balanced but the combination is not.
About mobile defense, I am not sure if the "fix" is in the right direction since AI and AT call-in vehicles like the Puma and C.PzIV again should not be allowed to be in the same commander.
