Yes, you can mix and match as you wish to achieve a balanced game on both Offense and Deffense. If you are struggling in a certain category then tweak the slider to something you are comfortable with. I am going to be making plenty of updates throughout the coming days.
My layout is pretty similar because of the 4 different sets but the sliders are different which is the main thing. Jarrod21 is great at making sliders too and I believe he is releasing some in the next few days.
