Concord now has the stink of failure associated with it now, no one will want to play a game which has such a reputation. Measures should have been taken before launch now it is too little too late.I think they have to do something, and making it FTP will attract a large number/influx of people.
Most people report the gunplay to be good, so it has that on its side, at least.
But yer, I am with you that I think it might not be salvageable, but they will have to try something.
