I agree completely 100%.
I think the key, like Armor has said hundreds of times is to keep what works, isolate what doesn't work (FOR YOU) and then make your own tweaks.
I firmly believe no slider set is going to be 100% perfect for you until you make your own adjustments.
I also think it's VERY important to TEST different things out and just see what happens.
There are so many bizarre connections in Madden with sliders and how they impact gameplay. So I think if you're not satisfied with the way the CPU is playing, try testing different variables - even the ones that seem totally counter-intuitive.
For me, that test came from bumping UP QB accuracy.
But - this does NOT mean that it will work for everyone! The only way you will know for sure is by testing on your own!
