Tested out the Defensive Commander for Ostheer, looks spot on to me, I don't see why all of the crying about being too similar to Osttruppen, Mobile Defense has Osttruppen as well and lots of other doctrines share at least 2 abilities with each other.
Are you serious? How can you compare the Mobile Defense Osttruppen with the one from Osttruppen doctrine. One is a 3 CP callin, the other 0 CP. They have completely different purposes.
The 0 CP Osttruppen callin is the "heart" of the Osttruppen doctrine, it makes it completely unique. Or you think anyone picks it for the officer or the railway arty?? Now the new defense doctrine even shares ANOTHER ability (trenches, sandbags, barbed wire for grens and osttruppen) on top of that which makes it even worse but it doesnt matter that much.
Seriously if you had to decide between
1) buffed Stug E callin + Pak 43 + buffed sector arty and
2) Officer + supply drop + railway arty, what would you choose? Hmmmmmmmmmmmmmmmmmmmmmmmmmmmmm
It's literally Osttruppen doc 2.0
