I disagree. I think it makes up for the lack of depth in creating a character.
What defines a character's forehand on this game? The forehand and power stats. But in real life, there is so much more to a person's forehand. Some people hit good running forehands (reach swings expert), some hit good inside out forehands (inside out master), some are good at taking the ball on the rise (semi-volley king), some are good at hitting when moving forward (approach shots expert), some are better at redirecting pace (shot counter), and some people are even really good at hitting very powerful forehands, even if they don't have time to take a huge swing (instant rocket). These are all natural abilities resulting from the person's technique, just like the amount of pace and spin they hit with.
A lot of the other skills are intangibles, or mental strengths, such as monster defense, and I agree that they have no place in a video game.
