Riot showed a system of 10 bans in the League of Legends

Since the beginning of this year, professional teams in the League of Legends have played in the conditions of the system of ten bans (there were previously six) champions in each game, but on the shared servers, ten bans will appear only in a new patch. In a different form.
Riot Games clearly demonstrated the system of ten bans for shared servers. Everything is simple enough: once the teams are loaded, both sides simultaneously get the opportunity to ban five champions - one for each player. In this case, they can not look at the opponent's bans before the expiration of the time allotted for this. After both parties have chosen their bans (this takes 35 seconds), the client shows which of the champions eventually dropped out.
The natural question is: what happens if two players from the opposite teams banned the same champion? From now on, bans can be duplicated, so nothing happens.
