At the beginning I have to say I found new CV very misleading.
It will be, because all that you have "learned" with old CV should be immediately forgotten as it can be harmful in the new system. Unfortunately there is no other way than playing more with the new CV and less with the old CV. After a while you will again have a proper "feeling" about what can be achieved by given combination of CV:CV. Attacking must be done at higher ratios now than before (no longer you can win 90% of the time when attacking with Soviets having 1:1 ratio of on-map CVs, most of the time you can expect your final CV in combat to be lower than starting CV - as it should be with elements properly scored and then dropping from combat due to losses).
All I can say - good luck!
