Premium Tanks should be only played with premium account

GeneralDirection: It's unlikely that this would be considered, primarily because premium tanks have a monetary value, so taking that away from players unless they pay more money, is not something we would consider. If we were concerned about the overuse of a certain tank (standard or premium), we would look at its balance numbers first.
But at the end of the day, if players are simply playing a certain tank a lot because they enjoy playing that tank, that's not something that should call for a nerf.
