Heavily Tested with:
FC Bayern vs Real, PSG, ManU, Chelsea
Barcelona vs Real, PSG, ManU, Bayern
Played atleast 50 games testing the sliders. Sometimes, AI would be bit too weak, sometimes too strong, etc. But I found a near-perfect combo for my use.
Matches were all played on World Class and Legendary. Sliders can be used with both difficulties. Only difference will be that on Legendary, AI will be a little stronger.
I made this in mind to remove CPU "super marking" and general "cheating". Try it out and post some results if you do.
User/CPU
Sprint: 53/50 (gives you a slight advantage with through balls)
Acceleration: 53/50 (same as above)
Shot Error: 50/50 (default)
Pass Error: 50/56 (CPU will have greater ball possession. This just makes it so cpu makes mistake sometimes. does not really affect scoring)
Shot Speed: 50/50 (default)
Pass Speed: 50/53 (gives cpu little boost in passing for faster play. corrected with pass error)
Injury Frequency: 50/50 (default but this is for you to decide)
Injury Severity: 50/50 (default, also you decide this)
Goalkeeper Ability: 50/45 (cpu cheats lol. You can even try 52/44)
Marking: 50/48 (possible 47 here. Gives you a bit space to play. cpu cheats)
Run Frequency: 50/55 (cpu gets little more in your face)
Line Height: 50/50 (default, this is still under testing but you can lower both by 4-5)
Line Length: 50/50 (default, this is still under testing but you can lower both by 5-10)
Line Width: 50/50 (default, this is still under testing but you can lower both by 4-5)
Fullback Positioning: 50/50 (default)
Power Bar: 50 (default)
First Touch Error: 50/52 (52 for WC, 53 for Leg. Leave yourself with 50 to learn it)
I hope you find this useful. I really have some great games now but as always, there is room for improvement
