I don't think it is ever OK to slag people off or talk down to people. Someone has obviously upset you. I don't know for which post or whether it was fair. If you think it unfair, there are official channels you can use to complain.
I think we all accept that many people have stuggled with FM07 and that errors and fluffed chances are the standard 2d representation of this struggle. What we don't accept, and have proved, is there being no way to counter this. You see frustrating defending. You vent. I see frustrating defending. I try to work out why it is happening. My assumption is: the match engine is not so flawed I can't do something about this with logical tactical thinking. Your assumption is: the match engine is flawed because my tactic has been working up until now. Fool me once, shame on you. Fool me twice, shame on me. Teams are doing something different against you. Work out how to beat it. The clue is: it's the small teams you are struggling against .
