To be honest, most of my all chat experience with the enemy team is positive. The verbal abuse rarely comes from the opposite team, who I usually joke with when I’m playing horribly.
Because of that, I do sometimes feed (unintentionally) and that causes the tryhards on my team - who obviously think they are better than where their ranking puts them - to rage at me. I do still play occasionally for fun but I’m not nearly the player I once was. I used to play competitively, but I’ve since had two kids and, admittedly, I simply can not keep up. I’ll be the first to admit that I’m not really great at League of Legends. Very rarely have I had a negative interaction with the enemy team. Personally, when it comes to toxic behavior and verbal abuse in League of Legends, I’ve found most of it comes from my own teammates. Players will still be able to communicate with the enemy team through emotes and champ mastery (unless muted) as well as champion actions, such as joke, taunt, dance sequence and laugh. However, with the rise of verbal abuse within the game, Riot has started to focus more on its chat systems. Riot has made a concerted effort to improve the behavioral systems of League of Legends, but most of the focus up until now has been on gameplay-based behavior like AFKing and intentional feeding.
