I love CS maps- they remind me of my childhood and I think they are generally well put-together and balanced. But remember in CS there are only two objectives or else it's elimination mode. Those same maps just don't translate in Insurgency because there are too many objectives which are too close together even for Conquest mode. I think we would be wise to avoid those, or at least keep them out of rotation for Checkpoint. They might maybe be okay for Outpost, but I don't see much other use for them beyond that.
