Yasuo is not the new vayne, ekko is the new vayne.
I heard it be said that yasuo was the new vayne, annoying to face but balanced anyway. Yasuo haters had some ground for hating him though, he did had a pretty OP bug and a 56% winrate, but ekko? EKKO? He's sitting at a 47.7% winrate and even when you calculate for his 8% winrate he is still 50% to sub 50% winrate. He's not fun to face, but he is no longer well performing.
For some reason the community still despises him(its probably his saftey). He is now getting pointless, tiny nerfs like 5 base AD(well i guess it will help with trinity force, but it's still pretty tiny TBH). Just like how vayne did in season 5. History repeats itself i guess.
