Ekko being strong but not insane like being made out to be

Ekko has become one of my most played champs and is my "top champion" on my main account atm and these are my thoughts and some other peoples thoughts on him.

I think he is above average strong, not Yasuo op, not Thresh op, but more like Diana release. He has so many problems lanning vs assassins like Fizz, Zed, LB, and Yasuo and Diana (to an extent).

Some of these post say his stun on his W is crazy and the shield is OP but I wont you to realize that it takes 3 whole seconds for this ability to cast, now how many champs trade longer than 3 seconds? and how many of these champs cant just move away from it or dodge it with ease? I do think the stun is CRAZY long though so champs that sit still for 3 seconds(for what ever reason) or are predicted are punished a little to much. The shield part is a little crazy to but the fact that it takes 3 seconds for it to come out hurts him.

On his ulty I feel like it could be used for 3 ways, to quick tp back in a fight, for damage, or for escape. I'm only talking about these 2 abilities because most people consider the other 2 ok and not a problem. Imo using it for damage can be avoided SUPER easily but people aren't playing around it, I feel like the giving him a big AP ratio on it is to just punish bad players. If you were going to nerf the ulty just nerf the AP ratio numbers (which is the obvious thing to nerf imo), I like the tp back in the fight because no other champ has ever had something like this where he can only go back on where he recalled.

personally: I REALLY like his concept and and how he plays BUT I do think he needs AP ratio nerf on his passive, w, and ulty.
