This is the stats for how many people are in champ for each role on the EU leaderboard since champ was added
The graph everyone uses is from mid season 11. There are 15 times more people in champ since that graphs release.
This image that everyone uses is 10/10 ragebait by the blizzard devs
There were like 5 people per role champ back then, now its like 300. Stop pretending this graph shows anything.
Using it just shows ignorance and invalidates any argument you make
