Let's assume you are correct. If the commander is not working well in 1v1's then it should likely be rebalanced anyway (assuming we balance for 1v1's), or it should be modified for larger team games because it tends to only see play there, and so changes have no effect on the precious 1v1 balance. Saying larger team games can't be balanced is nonsense since last patch we almost had a balanced 3v3 and 4v4 scene, literally less than one month ago.
In team games having an elephant and a stuka dive bomb is relatively easy, and causes games to end as you German steam roll the Allies off the map. The commander should be rebalanced, and I am all in favor of making it more attractive for smaller game modes, and improving its counterplay in larger game modes.
I have played the doctrine multiple times, and I usually don't have munitions stored up my rear that I can pull out and bomb the enemy into submission. The elefant comes LATE, and being expensive, slow, and lacking AI, it leaves the player requiring a strong infantry or much support from the teamate, which is where team play comes into effect. I'm with you balancing 2 vs 2 and above, but is this really the way? Is this Ostheer doctrine an issue? I think otherwise.
