I don't think we get comments like this without real pain behind them.
You like League, but it's hurting you. Worse: It's costing you time as it hurts you, which is a double whammy. You expect the organization that stewards this game to take it seriously, but your lived experience doesn't seem to be improving.
If nothing else, please believe that the enormity of the problem is not lost on us. You and many others are seen and heard and felt. Friend, we play the game, too.
There are many reasons why we cannot just Thanos-snap everyone who causes disruption in your games, but we are working on and testing a bunch of short/long term changes that we feel will help. These will get announced in patch notes and videos and the other ways we chat with players that aren't one-off Reddit responses.
Until then, I hope your next games are awesome.
