Riot Champion Select Lobby Suggestions:
1st - when a player on your team selects Mid - Yasuo Top - Riven Top - Teemo Mid - Lux Support - Zyra
For examples... a team mate should receive a warning screen advising them that a team mate has selected that champion in their role, and that banning a team mates champion is a reportable offense if done purposelyfully.
AFTER THE GAME,,,
Players should have the ability to report a player for an offense "Purposely banned Teams champion selection in an effort to tilt, be toxic, troll a game"
That Offense MUST BE added.
Next, champion select lobbies chat now needs to be reviewiable and reviewed by Riot because players are abusing the fact that "Riot doesn't read any chat other than in game chat".
Games are becoming toxic before a game even starts often. Then the player who starts the trouble goes into silent mute mode after causing all the trouble, confusion, and frustration in champ select.
Add a reportable option to Review Player X's champion selection lobby chat.
Riot, step it up. Your dropping the ball. Love you.
