The extreme slice serve: Down + Up + Safe Strike.
It's completely unrealistic and unfair since you can't come close to seeing the ball when trying to return it. IRL, nobody can hit slice serves standing from the middle of the court and spin them into the stands.

I strongly suggest removing it. There's already the normal slice serves in the game that work fine. This serve alone has ruined a few matches online for me.
But, it's of more concern for other players. I know how to combat it now by changing my camera angle to a wider screen, but most people aren't aware of these things (and ManuTOO can't say to do so since it makes the game look like crap...) If I was a new player against someone abusing that shot, I probably wouldn't have lasted here for long because it looks silly, and plays like cheating.
Just my opinion, do what we must. But, if we decide to keep it, I'll use it when I want.
