Dear league. Where will your playerbase go if you mysteriously removed ranked for an entire year? What then? Are you guys even in the position to try that? I've basically surmised that a lot of the toxic player base will leave or come out of the woodworks and finally reap what they sew by the true community who has been running league this whole time.
To keep the story short, ask yourself something RIOT. Do you plan on keeping to the path of causing unhealthy mental stress, or would you rather create great moments where parties of 10 can enjoy the same game? The choice is yours and inevitably, will most likely be of the greater evil rather than the lesser.
