Didn't think about if this would have any unwanted side-effects, just throwing this idea out there, add the, so wanted, RANDOM ARMY possibility and if you win, your rank increases by 15% more then it normally would and the opposite if you lose.
Sounds interesting!
Also speaking for myself;
I don't like soviets because they are so limiting. You'll rarely ever be able to build more than 2 tiers. Their commander dependance also adds to this feeling. I also find their stock units to be uninteresting compared to what you can get as call-ins. Gamplaywise they really bore me because you're bound to a handfull of strats if you wan't to win.
The USF on the other Hand I really like, but I think they still need some tweaking. Their AT-departement relies too heavily on Jacksons and I think their weapon unlocks also need some changes.
I really like the flexible design of the OKW and also think, that thy are the most interesting faction to play atm. They offer a variety of uniqe and strong units and have access to very diverse commanders.
Ostheer would probably be my favorite Faction if it wasn't for the inaccessebility of t4 and the low viabilty of t3. Unfortunately it's all about getting that Tiger out.
Of course I also prefer Axis because I'm a passionate Nazi
