Pretty interesting, some points that interest me or was sort of obvious but stated from first ~20 mins:
(first 20 may edit if not lazy):
-15 to 20 ppl on the balance team, sometimes 10-15, data oriented obviously (data for fun factor plz 😎)
-a champ is not strong in any skill bracket = buff but strong in any 1 = nerf also strong/weak vary by their skill brackets
-looks at Win and Ban rate, mastery data and riot has an understanding of how a champ is balanced or not at various skill levels and such
-everyone on balance at least multi season diamond
-at least 2 ppl per role and they put forth a list of champs that need to be buffed/nerfed
-aggregation of data from all the regions, China has some weird trends the team hasn’t really understood yet
-certain champs tilt players in regions differently (yuumi Korea and yasuo in China aren’t nearly as bad as NA salt against both)
-item wise before they nerf the item cuz it’s strong but now consider fringe users (still item rework was to push diversity right but when 1 champ uses 1 mythic or item set 99% time…)
-Viktor secret tech build: crown + lich bane
-they know corki azir is boring af and basically imply it won’t be at worlds (hopefully)
