Yeah I'm always reluctant to meddle.
Personally I find the way the difficulties work in these games very muddled, it's one area where I long for the simplicity of the original Don Bradman Cricket. I'm not aware of other games where you have both AI difficulty and then difficulty for how you actually play the game. Most games they are linked in some way. On the one hand I like the customization it allows for people, on the other it often feels like the game drifts too much toward a sandbox and it's a case of 'here's the basic game, figure out how to make it would for you.' From having the good fortune to be on the beta I know that's not the case but I could understand why someone could perceive it that way.
I'd sooner they intertwined them better or scrapped one - probably the AI difficulty choice - and work on getting a more consistent set of sliders for each difficulty. If you bowl lots of bad balls - regardless of the difficulty - the AI will punish you, if you bowl lots of good deliveries you will have increased chance of keeping things tighter getting wickets. If you get to a point where you are dominating/winning all the time then you increase the difficulty. You don't have to come on a forum and ask what needs to change because it's should be more self explanatory what you'd do. The default sliders feel a bit thrown together at times, some things are far easier to do than they should be and other things are far more difficult than they should be but they are all in the same difficulty level. I'd definitely reduce the number of difficulty levels. I'm not especially good at the game, but I can't see the need for any difficulty below Medium (I play on a half way between Hard/Hardest setting for batting).
I think the game should work for the most possible people straight out the box. For a smaller developer I think if you can limit the scope of the feedback it makes it easier to adapt and improve e.g. if you're getting consistent feedback by people playing on 'Hard' that the game is too difficult then the changes are easier than if people are playing on any of the millions of possible settings that are there with the sliders.
