Regular season: Best-of-1 (BO1) or Best-of-3 (BO3) depending on region; Playoffs: Best-of-5 (BO5); World Championship: Group stage BO1, knockout stage BO5
Why people argue about this
People often assume that BO5 in playoffs is just a random choice for excitement, forgetting that it's specifically designed to ensure more competitive matches by giving teams fewer chances to slip up. The confusion arises because they overlook how this format minimizes the impact of a single bad game and maximizes team strategy over luck.
