Riot Why

Can't we have a normal round robin where all the teams play each other in 1 split?

Sideshow has a video explaining why that doesn't work: https://youtu.be/xvFZjo5PgG0?si=zh9gd_9Yoy-JRN1e

Takes too long, only works in league because playing BO1s are easier without 7 maps. Full round robin would either be too expensive or take too long

because they want to be free to make LoL events at the end of the year

Riot is so afraid of splits taking long but the season ends months before the year ends and people have been asking for more games along with more time in between internationals. The reasoning actively disrupts the top teams from continuing to improve while forcing the struggling teams to have less chances to improve mid-season with their teams.
