This was discussed.
The way the doctrine system works now, if your opponent does not give any clear indications of commander choice until the ML-20 is built, and you have already chosen a doctrine without recon + Stuka, you are screwed. All the Soviet player has to do is turtle in their base, hold a VP and literally just barrage your base to death. It's not fun, it's not interesting and it definitely does not take skill.
Like I for one don't want to always choose Jaeger Armor(or whatever has the recon/stuka combo) if I see a ML-20 commander "just in case" they select it. It's BS.
I agree, it would mean choosing the same commander to counter all the time, in a 2v2 the chances for one player to have it is even higher. Kinda like the old ISU, elefant, stale meta.
How about the ML-20 would just rek bases a bit less or give considerable time to repair the bases between barrages. Remove chance to get one base down in one barrage, that is just .
I think if OKW doesn't place even one structure forward in a match, then the player is not playing to faction strengths properly, thus don't like the idea of being tied to base area completely.
The infantry blowing up in the base may not even be an issue atm, just have to take the ml-20 into account on the field and change retreating habits in that match.
