Hi
As we know CDC is rather unique tank, that offers unique game play. This game play only suits very experienced tankers as CDC has no armor, and any HE shell rips it apart. And any shot penetrates it. With new MM CDC faces tier 10s in 80% of the time and can offer nothing apart from lucky shot from 400meters.
CDC is mobile and has power but top speed of 55kmph really lets it down. The tank is huge and is easy target for anyone, and again having no armor forces this tank to be played as TD, a crap TD.
And when compared to Skorpion G, CDC loses in every aspect apart from hull traverse speed.
So what really this tank lacks is top speed. Please consider increasing the top speed of this tank to 65Kmph, and then CDC will be played as it was designed and will be able to offer something in tier 9-10 battles.
