So I forgot to report a player on the end game screen and I want to report him because he was being unsportsmanlike to me. Where can I go to report him outside of game? I've already went to Riot Games Support Page but I don't know what to do to report a player on the Riot Games Support Page. Any Help?
Unless their behavior was very extreme, don't bother submitting a Support Ticket. As long as one person reported him the match will be flagged for review, so it's typically not a big difference if you forgot to report.
If you absolutely must report something that you couldn't in the post-game lobby, you can use the ticket category I have a question > Game & Features > General Questions. Please don't use it for minor offenses, as Riot won't waste their time investigating anything the report system can handle and the ticket will just cause other legitimate tickets to take longer to be answered.
Support page -> submit a request (top middle of the page). Need any more help?
