Since my penultimate jump in tactic understanding, it's the computer who more often suffers that. AI needs several shots to get the goals while I can win with just a few. I have one screenie like that in the frustration thread.
As I say, there's one point of truth, bit it's not exactly that. Yes, you see several **** clear chances missed by your team and equal opportunities got in with way more percentage when it favours the AI. That much is true, but the problem lies elsewhere and is what is implied by my bolding of apparently clear chances. It would rather seem that when highlighting your best chances, the AI instead of highlighting best chances that are not good, in which the striker hits well marked or from awkward angles, it still picks a play in which you see the player alone against the goalkeeper, same as when the AI gets real clear cut chances. And that is what I'd say is the real problem, giving you a graphical representation that doesn't fit the actual worth of the attack when the play is the best the team had but still no good.
In a note that I don't pretend to address the point, as the point is actually more addressed by the above, the Barcelona-Chelsea matches had some so clearly cut chances by world class Drogba and Eto'o, where the goalies should not had any chance, yet they missed. It doesn't address because those were like the 3 in 1000 chances like that they miss while in FM you see players missing 750 in 1000 or so.
The thing is: it's not the AI doing any cheating, is the AI not knowing how to correctly translate into graphic what is what play would be happening.
The aforementioned screenie comes to show (from memory, can be slightly off):
Portsmouth (my team):
8 shots.
3 on target
3 off target.
2 blocked
2 clear cut chances.
40% possession.
2 goals.
Manchester United:
25 shots
13 on target
9 off target
3 blocked.
5 clear cut chances
60% possession.
0 goals.
My goalkeeper stopping a lot of shots that I was already thinking "oh damnit, there goes my match/my victory/my safe advantage (depending if during 0-0, 1-0 or 2-0, obviously)"
I have a few that I returned at the AI those matches of cursing at the AI goalkeeper.
One of these days soon, I'll try to dig some interesting thread from here and some years ago that helped me make the tactical jumps from my "AI cheats like **** it does" days until now.
