Not sure if I myself like this feature... there was a certain amount of suspense in close games previously, in wondering what effort your opponent might have run, and whether or not they GDP'd you and if so, if they were successful. Now one click can remove all that.
In my opinion, the problem with this is, if you know how good your team is and have a decent estimate of how good your opponents are, it's very easy to correctly predict who will win if you know the tactics, GDP and efforts used before the game is over...
I'll try to resist using this feature, though it may be tough at times to resist the temptation to do so when a team is doing better against me than I predicted...
