Many people predicted based on the last nerfs he got that a
is all it would take for him to be right back where he was. Honestly its not even that bad of an item for the old problematic tank Ekko, other than he didnt power spike as much with just it, but once he had 3 items and fully charged RoA you were kinda extra fucked because he was tanky and doing more damage than a straight tank Ekko. Still it was "safer" to build core tank items first on him, because that made him basically unkillable, and thats the point of tank Ekko.
If Ekko can kill you eventually, but you can never kill him, then he wins by default if you play his game... and since hes an over loaded "outplay" champ... well its really hard not to play his game.
But Riot can never admit they made a mistake, and in this case releasing Ekkos kit into the game at all, so we can never have a real fix for his state unless they just dumpster-gut his numbers so no one plays him and we can all stop worrying about it. Is that a good solution? No, but with Ekkos kit, hes like
and if their numbers are good, their kit cant be dealt with except by a few champs.
Then were stuck playing the pick X champ because busted OP, and ban the best counters to busted OP champ. This limits diversity because of the pick ban environment. The only solution to Ekko, is dumpster Ekko. His kit is as toxic as it comes, and if he has good numbers than he will see play and it will almost certainly be tank Ekko.
All that said, tank Ekko IS WEAKER than it has been in the past, not worthless, but not the broke OP flavor of the month level "I R teh good at LoLz cause I duz the flavor of the month abuse kappa 420 salt dank kek meme" that the kiddies pick up from streamers... that the streamers pick up from Koreans.
Tank Fizz is ugly, and with the tank Ekko nerfs, tank Fizz is now better. Of course Fizz is another toxic kit champ people would rather cut themselves than play against, but thats another thread for that discussion.
