In my honest opinion, the new patch added animations, the missing features that PC users got like the coin toss, doubles tactics etc... but the gameplay didn't really change all that much, the underlying issues are still present. The amount of times my player got stuck in the court and just stood there as a serve went by even second serves at 140kph... still a lot of those weird glitch movements where a player skips a few frames and appears at the ball, quite a few occasions I went to play a shot and nothing happened...
I'm sure some people will enjoy the game for what it is, but it's really hard since playing day one and having a fair amount of the issues still there today.
The drop shot is still the easiest way to win points, they changed the serving marker as well, only appears once your timing meter starts, so you've gotta focus on one or the other which makes things a bit awkward to say the least
Didn't appear to be any changes to the licensed players animations, John Isner is still serving a casual 260kph as well lol...
