I came to the board to say the same thing. I am a slightly toxic player, but I've been playing for 5 years and never gotten a ban. The thing is, i NEVER afk, or feed intentionally, or do any shenanigans in ranked. Yet I am matched time and time again with players who afk, feed, or take support then don't go to lane or w/e. Surprise surprise, placements come around, and 25% of my games have an AFK.
Like, what? A quarter of those games are statistically worthless for determining MMR? I wonder how I ended up in low bronze /s
I believe the solution to this is really, really, really twitchy banhammer and warnings. If riot doesn't want their game to be awful, don't let awful people do awful things. But no, Riot prioritizes having a bigger, scummy playerbase to make more $$ over having a slightly smaller, nicer playerbase. Award players who DON'T get reported with some kind of indicator in champ select/loading (for the team) or something. In fact, I'd say this is more Riot's fault than the community's. In the last 5 years, the numbers of AFKs and trolls hasn't appreciably changed, in my experience.
Who here would talk really negatively/swear/use slurs/ afk, if every time they did they got a warning, and were told if they did it again they'd get banned for 2 weeks automatically? I mean if it's really that hard to get banned, I might as well start afking if we start losing. Heck, I can keep league in the background while I play path of exile, and move my champ around a little bit. Evidently, this will make no difference for me, other than improving my personal experience.
