Riot seems to have a tenuous grasp on logic
Ever hear the popular phrase used in statistics "correlation does not imply causation". Riot commits this logical fallacy a lot. Just because x happened while y was present does not mean that x caused y. As I have bought more books, I have gotten older. Does this mean that buying books increases one's age? No, it is just a correlation. The same can be said for DQ. Since DQ and champ select were released at the same time, it is hard to differentiate between toxicity levels. Riot never shares their data nor method of retrieving statistics so it could be false anyway.
