That doctrine was never released because it was OP in general. 5 Panzer grenadiers with body armor, 2 flamers + satchels and smoke nades; normal mortars firing incendiary rounds; 160mp converted to 75 ammo, a forward HQ and that strategic bombing.
Bombing in base is partly true. It highly depends on the map. However, you are always able to place the hq in a safe spot.
I know, but why they put this ability in it was just, ugh.
And no, you can't always put your HQ in a safe place since the bombers can level any part of the map with the click of a button, including the base sector via many angles of ability activation. For a faction that relies upon strategic truck placement and territory denial to capture and hold fuel for their fuel starved income, it is an utter disgrace that one ability can totally destroy multiple tucks, even in one's base sector.
I am for removing any of these abilities that totally annihilate points on the map, including Axis abilities. This game should be about balance, not simply: 'I will wait until I have a lot of muni and then call in this ability to totally turn the game around'. This ability can totally change a game, without any skill involved, anyone can cap munitions points and defend them.
