Eh. I think they have to appeal to a wide audience. This means not making it so you easily get crushed if you're not playing the game of basketball perfectly. It would scare a lot of people away, and wouldn't be the huge seller that it is currently. In that sense, the defaults make sense in my mind. That's just a general feeling, I never really dig that deep into the sliders.It's been a while, but I'm fairly confident on default sliders every year there are several major flaws, like all dunks or zero dunks, or shooting percentages just being way off for certain situations. etc. I'm not saying I need the key to perfect realism, which requires a ton of accounting for individual skill issues, but just always surprised by the fundamental flaws baked into the defaults that have to be accounted for via sliders.
I definitely agree that it would be nice if they put a lot more time into preset sliders, like a "true sim" setting. Now that I think of it, that's pretty lame that they don't do this, considering the amount of long time fans they have.
Are slider settings downloadable from other users? I've never tried that.
