Honestly, OKW has no problem dealing with USF blobs (Kubel handles them well, doctrinal MG-34s). Don't forget, USF player needs muni and fuel to upgrade either LMG or Bazookas thus delaying teching and muni for abilities/nades. The problem with OKW blobs was they were too efficient as Shrek countered medium armor and Obers raped all infantry (no fuel teching + free LMG).
I think we all need to wait and see how the patch really is. I really don't think Ober nerf will hamper OKW as a army. I will pick Falls over Obers as a personal choice.
See? That's the problem. There is no reason to go for Obers because you can get a better preforming infantry unit with out having to rush a Schwer out. JLI and Fallsch can both come from buildings, and Panzerfuss are an excellent long range DPS squad to compliment your Sturms and Volks.
The nerf should have come with a price decrease. Not to mention the idiocy of nerfing the OKW blob and then refusing to look at Para 1919's or Rifle 1919's, since Infantry Company is basically the best/second best USF doctrine now.
