Fixing Toxic Online Behavior in League of Legends

First, the numbers are all given as percentages relative to a control. This makes the measured changes appear larger. If the control percentage was 5%, then a relative increase of 20% is just an absolute increase from 5% to 6%. (Also, the relative increase inherits variation from both the control and the target bin.)

Second, the data is presented as if it were cherry picked. They give the most interesting bins or transitions between similar bins, instead of discussing metrics over all of the bins.

I did a very rough estimate of the variation you'd expect to see, given 217 bins of binomial distributions with n=10^5 and p=0.05 where you report percentages relative to one of the bins. It's on the order of +-5%, despite the large sample sizes. Minor changes in protocol could increase this to +-30% and explain all of their results.

The wild swings when the color or font is changed increase my suspicion that they're seeing noise (because I really don't expect priming to be that strong).

Note that this is based entirely on the very superficial amount of data the presenter included in his slides. It may also be the case that they just omitted statistical details because they expected it to be boring to the audience.

Yes, there have been a few crazy strats, like the tournament game with the "jungle" Heimerdinger where they ran a push comp after their opponent picks had boxed the other team into a corner, but that sort of thing requires team coordination, in which case you're not worried about calling roles in the first place.

Matchmaking is a real problem and it sets people up for failure. There are plenty of people who are simply not prepared to jungle or support. Or, heck, depending on their lack of runes, they might not be able to tank, AP or ADC. You can say "you don't really need runes" but when you have little practice already, going in unprepared is only going to make it worse. I've supported without GP10s due to forgetting to change from a full ADC setup in champ select. It's painful, sightstone or no sightstone to be that poor, even if it was hilarious to ignite a poor, unsuspecting enemy Sona for first blood at level 1.

Sometimes you get teams of mature people who realize we're all in it to have fun, who will wait for you, crack jokes while you're all waiting, and generally make you feel better about the game. Those have been some of the best matches I've played, and included extending condolences to the other player when I've killed them and giving them tips on what they could do better after they respawn.

Other times, people will just yell at you, swear at you, call you names, constantly unpause the games, and just be horrible shits.

Also, I wonder what's different (culturally) about Russians, as they seem to be, by far, the less courteous of the bunch. I think they are racist towards Americans, so when someone speaks English, they basically go "fuck him, he's an American". A few of my friends go the opposite racism route, and say "fuck him, he's Russian", but I obviously try to tell them that you shouldn't be a dick to someone if he's not been a dick to you first.
