Germany have more than Soviets attacker division 50% expirience, morale and first strike tactic in 1941 and the best leader, why is posibiliti to grow Soviets CV?Yes, there's kind of conflict between removing 1->2 and using mild blizzard at the same time. Perhaps the blizzard could be less mild without 1->2 (or 1->2 should not apply from December). Players will have to experiment and find out what combination they like.

Also, Germany has very poor command chain (non-existent), this costs them much more than 20% CV, check division roll chances in supply window.
