Clearly the balance has been established.
I feel that D class CCs are acceptable as they are out numbered, less armored, less beefy, less armed, than their counterparts.
I by myself feel that I am not capable of taking out 6 SO, 1 Riot control, and 1 star. It should be obvious who wins in this case.
The only possible balance change would be lengthening NLR for D class CCs, as the battles tend to be about attrition rather than a decisive moments.
