We've been getting some free win reports cause of no replay. Just because this announcement was made a while back does not mean it no longer applies!
If W:A doesnt save replays, it's your responsibility to fix it. I use windows 8 and I have no problems at all with replays. So it's a problem that can be fixed. If you decide you dont want to go through the effort, that's your choice, but then t's your responsibility to get the replay from your opponent.
