I think their stats are bogus. When they say toxicity is down I think they mean the number of people actually punished. Tribunal has been gone for years. The system has pretty much been automated this entire time, yet some peoples reports such as myself are totally worthless. To the degree that I've had people call me n*gger in game, wish death and disease upon me and my progeny etc. All the things they supposedly have automated systems to pick up on. I haven't gotten a single message saying anyone has been punished. No matter how hard they raged, fed, went afk whatever the case may have been......they still played every day after that. I know because I'm petty and I look. So the question becomes....how many people's reports have just been marked as frivolous? Did an actual human being go look through all the reports one day I made and decide none of them were worthy? So now people can pretty much troll me with impunity. I've had games I'm sure my entire team reported someone, plus an enemy or two. Still nothing. I think that's how they skew the statistics.
How many thousands and thousands of players reports have no weight? I mean if everytime I report someone you never punish them, and everytime I report someone who doesn't get punished it lowers the weight of my reports.........someone has to see the vicious cycle being created for certain players. This is why so many people bitch about trolls yet Riot staff comes with these statistics about the small percentage of people that are being problems. They are only counting the people they punish. AFK's are supposedly rare and everybody has the same chance of getting them, but I've had 3 or 4 in my last 5 ranked games. 2 in the same game. ALL were rage quits not connection issues, and ALL played more games afterwards. Now all they have to do is play another 10 or 15 games without afking and they can screw someone else over with zero repercussion because that's how the system works.
