What this means
From the video: Vambient's breakdown, lightly cleaned from speech
Not very banned. Not banned a lot of the time and not bit higher than Ashan in terms of pick rate. We are seeing Riven at the top.
Ber has been at the top for a very long time. Been a rank one champion for a very long time. Has received nerfs recently.
Has not stopped him has not stopped her. Bourbon from I mean not a single diver rank one player but has not stopped him from being rank one for the longest time. This is a rank one champion.
Very valuable honestly. Like if you wanted to play Palin and I don't know if you're not playing Riven, you know, like rethink your life. No, no, I mean it's fine.
But it's like this is this is one of the endame champions in League games.
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.
