I really don't care about the play of the games anymore. I think they might go by damage done/kills in that short amount of time. I have seen some pretty shit potgs but I have not put too much thought in it.
As for the nerfs which have been applied, do you guys see any major differences? As I have witnessed today, Mccree still shits on the lives of nearly everyone he encounters, and widow still does crazy amounts of damage. I can tell she was nerfed a bit, but she does take out a large portion, if not all of your health in one hit. Neither of the two can half health tanks though, so I guess that is good.
