Then it isnt a league. In a league plays every user against every user under the same requirements.
Hi,
It's a league, and actually is the system followed in several countries in Latin America: 2 championships or leagues per year, in the first semester (opening season) teams play once between them except for the "clásico" or derby, which is played twice (home and away) per semester. In the second semester (closing season) is the same system, the only thing that change is that the x-team that played at home against y-team, in the closing season x-team will play away against y-team. The "Clasico" is also played home and away.
