Apologies if this has been answered before but...
The slice shot.
Sometimes it works as intended, but most times holding the slice button (Square on my DS controller i use on PC) doesnt result in a slice, but more of a topspin backhand shot with no slice that often goes way out.
Im thinking that surely this isnt right, even with little preparation time or a lot, the result is often not the slice i want.
Any reason this could be happening?
