There's nothing wrong with using offiside trap and counterattacking. Won the league last season with both orders on (NFC Kuching), finished second with Go Leo.

Real Messy has joint least goals conceded in their league and is currently sitting 2nd but level on points with leader, NFC Kuching has the best defence in their league - unfortunate to have 2 very high Q team with them.

The only way you could get punished for using offside and counterattacking is if A) The team is WAY WAY stronger than you or B) You come up against someone playing ULTRA DEFENSIVE + COUNTER, which is quite rare.
