I've actually fixed that silly panicking ai by upping the levels to 5. Might be high but looks much better than rushing back to defense like mad men IMO.I'm not in front of the game right now, but Im' sure in my livestream archive it can be found somewhere .
My approach with the settings/tactics, etc. is that it is great they exist. I do not think that they are the #1 controller of the attack/defense level. This may make it more clear, if you didn't have the sound on...
Best case scenario, with proper transitioning:
Team1 attacking, Attack level = 4 (1-5 scale)
Team1 dispossessed, Defense level = 3 (1-5 scale)
Team1 defends in defensive third to 18-yardbox, Defense Level = 2 (1-5 scale)
What happens in PES, and needs to be fixed.
Team1 attacking, Attack Level = 4 (1-5 scale)
Team1 dispossessed, Defense level = 2 (1-5 scale)
*As you can see, they jump straight from Level 4 to Level 2, bypassing Level 3. That results in the ultra-retreating and ultra charge. This makes it more end to end, and makes the CPU offense passive when they've lost possession, or even a 50/50 ball occurs.
