If you are a 3.0, be the best 3.0. I don't think your strokes are that advanced or you would be rated higher. There is a lot more to a stroke then just being able to hit it when you get a perfect ball. You need to be able to hit off balance, on the run, backed up..etc to have advanced strokes. So just go out and play tennis and win matches. Don't worry about the other person's feelings and develop a winning mentality.
