Saying someone's sliders are not good obviously is your opinion of which you are certainly entitled. If something feels off to you like game speed why not simply reduce it? Everyone who makes sliders makes them according to their personal vision of how the real game is played. This often takes time to get "perfected" because one adjustment can throw several other things out of whack. Nothing is set in stone and you can feel free to use any slider set as a base and tweak to your own liking. If you disagree with how these sliders play out then fine but saying that the are not good seems a little over the top. Also, no disrespect but perhaps superstar is too high of a level for you to be playing on.
