[2019] How are the new Ruski BBs?

Hey Captains,

How are you liking the new Soviet BBs? What are you finding to be successful playing them and what would you tell other players that haven't tried them? The correct answer is not "they are OP and destroy everything else", the correct answer would be what their strengths and weaknesses are. For instance, the Kremlin has great deck armor that is resistant to fire but has a citadel that can be punished if exposed.

Thoughts?
