@Raykco: No i dont think its because of the quality difference. I play level 20 and that shouldnt be a big difference to lvl 18 or 19. And believe me, im a well experienced player. So i think we can exclude this.

@OBree: I dont think its about tactics too. Or the tactics just changed completely and is really unlogic now. I would say im really experienced in tactics and i face the problem too. Even if i could do something a bit better that doesnt explain such a dramatic change. It changed from winning every game to nearly none...

I realized tat many of the games end draw. It seems like the engine tries to make the team with less goals score all the time, even if its unrealistic. Example: A few days ago I had a game and scored first time. Enemy was attacking through the middle (wingers only dl and dr). And i played defensive with with many players in the middle (dmc 3 mc). Enemy had a counter attack every 5 game minutes and suddenly stopped having after he scored?! First conclusion: You shouldnt face so many counter attacks if you play defensive and your formation is adapted to face the enemy attacking tactis. second: Why did it stop after the goal?
Perhaps this was just coincidence but with the general phenomenon (which is definetly not coincidence) its quite suspicious...
