Always been a fan of permanent formations. But then again, I have more 2nd placed finishes than first place, so maybe that's why. I play the game for fun so maybe that's why I do not bother playing counter formations much unless I fancy a challenge.

But here's wht I can share abt playing one formation throughout the season. If your team is on a good run, you can always expect you can beat the next guy regardless of team quality. This game is about having the right kind of players in the right formation, or playing the right formation to suit the players you have.
