Yes, these commanders I don't have.
What about the Luftwaffe Supply Doctrine commander? Isn't that good for 1v1?
Close Air Support is generally better than Luftwaffe Supply because of the anti infantry strafe. Both crutch hard on the Supply Drop to work though.
Joint Operations has a wasted slot because you can't really get away with making both a Pak43
and a leFH. That's just too much pop and resources invested into static units asking to get overrun by a larger army.
Storm Doctrine requires allot of effort to get to work because it has allot of situational abilities (Riegel, leFH, Stuka Bomb) or abilities that require effort to work (Ambush Camouflage, Smoke Bombs). Other doctrines tend to have a more easy pay-off, but if you can master the abilities the doctrine becomes pretty good. Not for easy wins.
Scavenge Doctrine is a solid doctrine, just not top tier like Luftwaffe and Grand Offensive. Every ability on it is good (even Advanced Scavenge since patch), so it doesn't hurt to have it in your loadout.
