This is rather dated post but consider this on What About Clients? which was written by Holden Oliver and particularly:
"Litigators are like nuclear warheads; everyone has to have them--but once you start using them, everything gets expensive and screwed up. Litigators know this better than anyone. Hull McGuire does commercial litigation, lots of it, and we love doing it. But even in the best of cases, no one ever "wins". Like war itself, commercial litigation is a last resort, and an inefficient way to resolve virtually any dispute."
In my view, more incentive to mediate particularly when the view point comes from such a respected law firm.
