First off, Riot, please sort out your reporting system. It's a little bit ridiculous that you can only report a player on the post game screen, and that only the in-game info is available, not the chat before or after games.
Anyway, I need to report a player for SERIOUS abuse, we are talking hate speech, intentionally trolling, the works. However, my internet connection cut near the end of the game and it couldnt reconnect me so i couldn't put in a report (hence why you guys need to add another way to report).
So if someone could contact me that'd be great, I have screens of the offenses too btw :)
