What? I don't even...
I've only been playing for about 3 weeks now so my knowledge is a very limited about soviet industry commander (I don't have it), but as a whole there doesn't seem to be much hurting soviets overall.
The only thing I see relevant as nerfs are 1 to 2 cp for shocks/guards. Most games I already have 2-3 cp by the time I need to call in a shock/guards. Learn to use your core army first before relying on clutch call ins like shocks.
T34/85s got pushed back two whole CPs. That means that anyone going straight for them is going to have to hold out much longer with infantry then they did before. It's defenetly going to hurt.
I'm also pretty angry about the arty being pushed back. It's hardly used already, I thought them getting pushed up a bit really helped their utility and didn't really hurt either side.
