So I just got done playing a match for the first time in a few days and there is a problem with the volley mechanic. I will hopefully have the video uploaded to YouTube within a few hours, it's a 30+ minute match so I'm not sure if I'm allowed to upload files of that length, but there are many instances of this player hitting the netcord intentionally on his drop volleys and other volleys. What this does most of the time is "stun" the opposing player so there is a slight delay in getting to the ball or your player will stumble. This almost guarantees a winner for the net player hitting the shot.
The netcord is not always visible, but there is a clear and distinct noise of the volley hitting the netcord which can be heard clearly each time they hit the volley. I should have the video posted in this thread by the end of the day, it takes forever for files that size to upload to YouTube so I will post it as soon as it's done.
EA needs to patch this immediately.
Edit. Here is the video, long but many instances of the netcord volley.
