I tested beta but unfortunatelly I didn't have the chance to play so much against real players. Quite few players there, I had 4 maybe 5 matches against real people. Made some tests against CPU but these are irrelevant. CPU won't never attack you with double bar blobs.
So based on my low player vs player experience in BETA, these are my conclusions:
- Speaking of USF I concluded that the fast teching is still their best bet, not the double Bars and such. They appear to be more viable now;
- Wehrmacht is doing fine in my view, you have enough options to answer to different strategies. The only shitty thing there, are the vanilla grenadiers that are still dying like goofy chicken. But if you resist in early game, don't loose to much territory or to entire squads, you have prety good chances. A faction for skilled people

;
- OKW is doing fine, with the kubel fuel cost and everyting. I didn't observe changes, kubel is still usefull but now you can actually hit it and that's a good thing. Requires less skill than Wehrmacht though;
- Didn't have the time to properly test soviets so I can't say much about them but seemed that are no important changes except that the cover system serves them well with their high numbered squads.
Hope this was usefull.
