Is there a way that i can have high ic as germany without shitting out? To counter this, i usually upgrade all my provinces to 4 AA(is this sufficient enough to hurt strategic bombers and protect industries?) When i finish upgrading AA to 4, i stop all provincial upgrades in a province with 4 AA and work on coastal defenses or giving the west wall some land fortifications. Whenever i do this, i usually feel a bit underteched in air(i usually upgrade tanks and infantry during pre-war period). My question is basically, how can i keep a high ic as germany without having to put the entire country in provincial upgrade mode?
