Mechanized doctrine: Replace LMG Grens in 250 with buildable 250 from HQ. Replace LeFH with mortar HT.
Disagree entirely. Both LMG grens are LeFH are interesting aspects to combine with spot scopes IMO. I wouldnt change those. They dont sinergyse as Mortar HT or buildable 250 but thats the point of it, having different units for very different situations.
"Usable" is a rather misleading term. I would expect we are talking about 1v1s since the most skilled players care more about that game mode.
I would change for OST in the Festung support commander the reserve battallion (the ostruppen refund ability) for either paradropped supplies (Amu+Fu+MG34+Pak40) or the super bunker from defensive community commander
For SU i would like to see more radio intercept commanders, maybe for de NKVD one.
For UKF i would remove the defensive formations (? (IS builds emplacements) for assault IS.
And for OKW i would remove the LeFH from the defensive commander, maybe for the new commander defensive bonus for infantry.
I would also swap the Stumtiger from Armor elite with the command panther from spec Ops
As for USF i would change M36 for M10, always. J/k
