Riot's ban system needs serious work. Inappropriate behavior justified by group play.

Had a game in League of Legends where there was a 3 man group on my team. I was getting very annoyed with the support (I was Kai'Sa) and asked Ryze (who was in the trio) if they can swap me for lane phase. His response was, "If you don't go bot I'm gonna int this game." I did not go bot and he inted the game as hard as he could. He used hate speech and foul language in chat while doing this. When he realized he could get in trouble he had his other 2 trio players int as well. The Master Yi in this game then proceeded to use hate speech and curse as well. Meanwhile I'm not typing. They put up a surrender vote and myself and the other person not in the trio vote No. More foul language and inting from all trio ensues. They will probably be saved by the shield that is playing in a group. Riot is greedy and doesn't care about the odd man out. Instead because this game promotes playing with your friends and by association gets Riot more money, they will turn a blind eye. Riot needs to look into cases like this and not let it slip by. This is a common occurrence. It is unfair and makes the game unfun and stressful to play. Riot. Do something please. https://cdn.discordapp.com/attachments/212397717060714496/556345770299752498/unknown.png
