All professional matches use Captain's Mode drafting; Each team bans and picks heroes in an alternating sequence; Draft order: Ban-Ban-Ban-Ban — Pick-Pick-Pick-Pick — Ban-Ban-Ban-Ban — Pick-Pick-Pick-Pick — Ban-Ban — Pick-Pick
Why people argue about this
People often assume that in Dota 2's Captain's Mode, you only get one chance to pick a hero per team during the entire draft process, which leads them to misunderstand how the alternating Ban-Pick-Ban-Pick structure actually works and can lead to more strategic debates about timing their picks or bans.
