Coz static artillery emplacements worthless against CAS or Luftwaffe?
And what?
Being gimmick not makes it bad.
No, completely overshadowed by doctrines i listed. B4 would be bombed by CAS before it inflict any serious damage, better to play without commander then go b4 against CAS.
Airborne simply best USF doctrine. In 3 sov + 1 USF scenarios USF player should go airborne every game.
Most people don't expect static emplacement artillery anymore since the B4 change, and are unprepared to see people still use it or make use of the ML-20.
Not to mention terror doctrine has access to fear propaganda AND the ML-20 allowing you to hit the double whammy of forcing a retreat then smashing an HQ.
The no elite infantry from armored assault makes it garbo because you need to capitalize on Allies early game power, and T34/85's AND IS2's in the same doctrine is dumb and redundant when the other IS2 and T34/85 commanders are much better anyway.
The Shock ISU is better on smaller maps.
And Airborne isn't by far the best and only doctrine you have to go in 4's, for example Recon Support is great for the artillery call in.
Not all doctrines are equal, but pretending Allies lack for viable commanders in them is laughable when both sides are shoe horned into taking a select few commanders if they want to play
optimally.
