Hi Manu,
I was able to play a lot of matches recently, all offline and CPU in Pro-5.
I found drop shots very ineffective atm and I can't perform drop volleys as before, they always end up too wide. I remember a few versions ago there was some controversy around drop shots so I know there were some movements in that regard.
Unfortunately I don't have any suggestions to make, just wanted to say that I found it very difficult to make an effective drop shot (even if I'm well positioned and the ball allows a drop shot) and now I almost never try to rush to the net as drop volleys are not as they were before.
Game is still fun AF anyway, but I think it can use some revision in that area for the future
