To be honest, yes it is too much. The game experience should scale with preset options & difficulties. Sure, add a 'Custom' option that lets you tailor individual sliders to suit, but the sliders shouldn't overlay on top of the existing difficulty levels as some sort of multiplier, they should dictate the difficulty level.
Racing games are a pretty good parallel - some people like to race casually, some want a more hardcore sim experience. Look at F1 2017 - Easy sets AI to easy, you can have auto gears, driving line, braking assist, etc. You can then also go customer and leave AI as is, but disable auto gears, braking, etc to make it more challenging. You don't have a slider to adjust the default level of grip, or the lifetime of the tires, or the acceleration of gravity - these are constants of physics and should remain consistent in cricket as well! Don't give me a slider for pitch friction - this should be dictated by the type of pitch! Don't give me a slider for ball speed, increase ball speed with difficulty... Similarly with shot power, don't give me a slider - someone can either hit the ball hard or not and should be dictated by player attributes!
It just seems lazy to add sliders and say - go sort the difficulty out yourself, by the way we won't tell you what half the sliders do (because we don't know ourselves) so go and work it out on your own.
I hate comparing cricket games to FIFA, but in FIFA, to get a decent game, you don't need to edit all the players to have 1 skill vs 100 skill on opposing team. In FIFA you don't need to pick the worst team to play against the best team on Legend difficulty to have a good game. It should be handled in the design and not up to the user to customise the game to the nth degree.
