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 think that the Ban-Pick-Ban-Pick sequence is only for selecting heroes from a pool of 10, but they forget about the actual team bans which can target game mechanics like lanes or buffs, leading to confusion and arguments over what exactly constitutes a valid ban in Captain's Mode.
