It seems like Quality, Attendance and Tactics mean Nothing in this Game

[Lucian1986]

well, that's a wrong sentence.
The question is how often Quality, Attendance and Tactics mean Nothing in this Game ?
That's what I investigate.
I saw hundred or thousands comment about "I had better quality, full condition, morale, bonus, support, right tactics and oppo manager wasn't present".
But I never saw a post saying that "Me and some other managers had better quality teams, were active,..., but at the end a much weaker abandoned team won the title".

Not sure what you are getting at there. You don't need a weaker abandoned team to win the title to feel cheated. Having a much weaker team knock you out of the Cup, Champions League or compromise your League title chance is enough.

From my scouring the forums, a 15-20% difference with an abandoned team is approximately the point where people feel cheated.
