the stronger the region, the more toxic it is in most cases and it's no coincidence
"toxicity" is really just people being competitive and actually caring about the game. if no one cared, there would be no emotional involvement and thus no toxicity. would you get mad if you lost in candy crush or something like that? most couldn't care less and in fact these rather extreme definitions of toxicity are turning people into casuals who no longer care about the game because they've been conditioned not to by Riot's own system.
on this server, you can't even talk about builds or strategy without being considered a "flamer" or "negative"
it's way beyond what used to be considered verbal abuse (personally attacking someone... not just gameplay related comments) or negative attitude (giving up on the game @ 5 min etc.)
you can stay bad in your little "toxicity free" bubble or you can learn and let a competitive game thrive. the cuts and bruises to your ego will heal soon enough and you'll have grown from it both as a player and as a human being with a thicker skin. the more you try to censor and control people, the less people will want to play (especially serious games) or even to use chat at all. there is a mute button and only serious harassment/inting/afking etc. should be punishable.
stupid shit like "ggez" or "your build is awful because it lacks void and they're stacking MR" does not qualify. the worst part is that the true ragers who instigate and harass for no reason can't even be called "pathetic losers" because that gets you into ban territory yourself. it verges on absurdity and it hurts the game more than Riot can possibly comprehend. the system is completely off the rails at this point and getting $ from new accounts won't save it from the damage inflicted long-term. right now it's actually punishing victims and serious players who CARE.
