Champion Selection
When we play Blind Pick, we call our lane to secure the position. But miscommunication happens. Players who come to the room late cannot read what lane was already taken. When more than 2 players call the same lane simultaneously. they have to quickly change the lane. Thus we can end up having two junglers, two tops, no support etc. Instead of calling the lane, if Riot provides position boxes and each player click where they want to go, we can simply avoid this miscommunication.
