For what it's worth, when I played the 18th hole with three members the week before last, One of them missed the fairway off the tee, deliberated as to what to do, and then played a courageous shot from the rough up onto the second fairway. That aspect of the hole worked as intended, IMO.
It's certainly possible for the rough along that fairway to be so dastardly that attempting to advance the ball to the next fairway becomes a no-go, but is that a matter of design or maintenance?
Re: the in-course OB, it's largely yet another consequence of the club & ball issue.
