I hope they don't move the FR-S to DS just so it makes my decision easier to go back to KM.
But seriously, the explanation from the SEB member makes sense. Why would you want to bury a car that brings in a large amount of participation? I would imagine that instead of having CS at 86 drivers and DS at 31 drivers, you'll probably get them more even and have ~60 drivers in each class if the Twin is moved to DS.
