Should NFL OT rules change?

I think that if the format stays the same with coin toss and team who scores first wins, I believe that a touchdown not a field goal should be required to prevent fluke plays or I think both teams offenses should have a chance to outscore each other like in college. Just because a team gave up a score especially a field goal on the first possession does not mean that there defense was not good. So it is stupid when people say that NFL OT forces team to want to play a better D.
