What this means
From the video: Vambient's breakdown, lightly cleaned from speech
Kha'Zix, on the other hand, I'd say pretty bad to main. He's very popular as a pick. 4% of games that he's picked 2% ban rates and three challengers, six GMs for it.
So he has similar showcase to Kennen. He's also very mechanically def demanding because you have to not die as a bug, a very squishy bug. So essentially you have to run very quickly, jump everywhere and not die at any point during it.
Otherwise, you're basically throwing the game if you're spending most of your time, you know, dead.
How this was measured
Two numbers, one division. First, how many players are currently in Challenger or Grandmaster maining this champion in Korea, Europe West and North America, from onetricks.gg. Second, how many ranked games the entire playerbase plays of this champion worldwide across every rank, from op.gg. The result is high elo mains per 100,000 games played, then reduced by the champion's ban rate, because a champion you cannot pick is a champion you cannot main.
This is not a win rate list and it is not a patch strength list. It measures availability-adjusted high-elo main density: how much Challenger and Grandmaster main representation a champion has relative to how often it is played. It is not the probability that maining this champion will get you to high elo. The score counts Challenger and Grandmaster mains only, drawn from a tracked pool that starts at Master; it does not include the Chinese server, and it counts accounts rather than people, so one dedicated player with several high elo accounts shows up more than once. Patch 16.15. The full plain English explanation, including everything this list cannot tell you, is on the main list page.
Popularity is not the signal. What matters here is how densely high elo mains appear relative to how often the champion is played.
