Ok, I guess, but plain old non exit row 16c would have beaten the heck out of the last row on the plane. And with any warning at all I could have changed my plans to work around the change. Is there no way to have alerted me of my problem?
It's interesting, you had a fare sale after I bought this ticket, and I didn't cancel and rebook because I didn't want to mess with the seating.
