1 Can we make baseline winners easier?(when fighting to the CPU) Now even in the grass it is so difficult . (I remember the TE 2004)
2 we human players need to change return direction more rapidly in some situations.(but if we can't, it's not a big problem)
3 make smash harder to defence(especially when the defender is on the volley, in fact we should not able to defence)
4 The errors shouldn't always be "OUT" , sometimes it causes by lower height.
5 The errors shouldn't all count to the "unforced errors"
6 The forehand should be normally much stronger than the backhand!!
7 The slice is still not so effective now.
8 The drop shot or the lob should be much easier to fault.
9 For CPU players, he is too strong in volley but in the other hand if we give him a drop shot he makes fault easily.
PS: My english is not good.
