I don't think ekkos problem is in his damage.
his kit. is just plain. too much mobility for him. and cc for enemies. hes still too strong as a tank. and even stronger as an ap. the thing is they can't give him the burst of fizz or leblanc because then it will be a problem where he has much more utility than both of them. hes not an assassin hes i'd say a diver or fighter that has too much slows and cc and speed ups. hes still too nasty anywhere you put him. sorry but a champion that has 58% winrate isn't gonna be fixed with that sorry ass nerf you put on the pbe.
