Thinking of OWL, if you have like 6 or 8 teams in the league, then what, 2 or 4 make it to the play offs? It just doesn't sound fun unless there are at least 12 teams participating, and ideally something like 16, and then contenders.
Here they will have an 8 team league with a 2 team play off. If that's an OWL preview, i'm not all that excited.
Contenders season 0 with 16 teams in 4 groups is just better. In a proper league format instead of groups it would be something like NBA's divisions, which have cross divisional play.
Of course since they want massive buy ins, we probably literally will get a 6 or 8 team OWL in season 1.
