Instead of nerfing meta, how about buffing non meta?
I can list champions that are not at the top of meta meta and usually are not played in pro scene unless it is a niche counter pick like poppy into irelia, bottom food chain, most of these champions have 0 games played in worlds 2019 or were only used to niche counterpick:
(lane karthus, not jungle karthus, jungle karthus is broken)


(how do u even play darius into fiora, lmao)


strong or recently buffed champions in these recent patches that don't need buffs or nerfs but aren't top of food chain meta either, which some being at the top until riot nerfed them after worlds like pantheon:


Champ almost broken:
champion i think is absolutely broken but not too sure:

champions rito should fucking nerf at top of food chain:

please comment on any champions i miss, or if you believe a champion should be in a different category, with stats either showing that champion was never played in worlds 2019, or had high presence in worlds 2019, but remember the nerfs on patches we already had after worlds being an exception, such as the pantheon nerfs after worlds but he was broken in worlds.
